      I was charged with over a dozen transactions with this company's name of varying amounts on my debit card, stealing the $1,500 had in my checking account and claiming that I owe another ***** on top of this. This company is headquartered in *****; I live in ****. I don't buy anything online except on Amazon. This was my rent money. Somebody using this company's name, or the company itself has robbed me of that money. I want every ***** refunded immediately

      6 Months of processing just to say they don't accept credit cards. They cancel your transactions then require you to do wire transfers.

      We apologize for the experience. Unfortunately, we will not be able to process this order with the requested credit card terms. Should the customer still have a need, PayPal is an available payment method for orders placed through our website, www.mouser.com.

      Date of transaction in dispute: August 21, 2023 Web Order no. ******** Invoice no. ******** Paid with **** 8-21-2023 Mouser Electronics shipped this order to the incorrect address and decided to ship it to the correct address without charge, authorized by the customer service rep. *************************** *********. The original order was recovered by a neighbor nextdoor to the incorrect shipping address. This order was approved for return to Mouser on 8-30-2023 by ******************************* who provided a return label. The package was received by Mouser and *** provided delivery tracking confirmation ****************** on 9-6-2023. This tracking number shows up delivered on *** website.Mouser has called me at my office and accused me of not paying the first invoice of $314.56 and has billing history for the same order in triplicate. They have refused to resolve their accounting errors and instead have placed my ability to place orders on hiatus, not accepting payment. I have sent Mouser Electronics screenshots of credit card statement showing payment, *** tracking confirmation, etc.. I feel that Mouser has intentionally created this issue, and its resulted in my having to spend an inordinate amount of time attempting to reach a resolution that Mouser apparently wishes to ignore. I would request BBB intervene on my behalf, as I have exhausted every avenue to achieve resolution through Mouser's customer service options. Attached is a screenshot of my credit card statement with the Mouser Electronics payment showing on Aug 21, 2023 and *** delivery of returned duplicate order.The irony in this is that Mouser shipped the duplicate order to me as a professional courtesy at no charge. When I received the original order back from the incorrect delivery address, I requested Mouser to issue a return label. No good deed goes unpunished by this company I suspect. I was doing what I considered the honest and correct thing, return the second order. I assume that is the problem.

      We order 120 pcs of fans (P/N 978-9GA0612P1H03 ) from Mouser Electronics on 8/3/23, and received them about a week later. Upon income testing, we found 80 pcs were defective and requested to return them. Mouser promptly provided the return shipping label and we shipped the 80 defective parts back. All parts were in the original package and the only thing we did was powering them up to check the ***** level. The tracking # was 1Z7759459048201813 and the return was delivered to Mouser on 9/18/23. Mouser has not committed to refunding us dispite our repeated inquiries. Now that they have received the return for over a month, and they are not responding to our threat of filing complaints agiant them with BBB and other government agencies.

      Our sincerest apologies for the delay in response.
      A voice message was left for our customer on October 30th. A full refund has been applied. We are currently waiting on a response from the manufacturer regarding the defective product. As soon as we have received a response, we will be in contact.

      Found a pending fraudulent charge on my credit card. Called Mouser the same day to report and the company still went ahead with the charge even though I asked them not to charge my credit card or ship out any products. Called again a week later and nothing was done.

Additional contact with the consumer is needed, so a member of our Customer Accounts team is reaching out using the contact information that was provided. If the consumer has not heard from Mouser, he can reach out to us directly.

      I purchased electronics parts from Mouser Electronics back in April 2022.Order # ******** (attached).One of the items on the invoice was 40 pieces of TIP2955 transistors (total $40.60).When I attempted to use these transistors in the actual project (in Jan 2023), upon closer examination it turned out that these transistors are most likely FAKE or at least mislabeled.Their parameters do not conform with official datasheet, as far as their electrical parameters go (e.g, Hfe specified in the datasheet as "min. 20", and measured Hfe being 12 (as seen on the attache photo),but most importantly, even order of pins of these transistors are different.Pinout specified in the datasheet is B-C-E, while transistors sold by Mouse are B-E-C - which basically means that totally DIFFERENT transistors have been packaged in TIP2955 case, with TIP2955 markings.Attached a photo showing different actual pinout of fake transistors.B-E-C pinout for this kind of transistors is only used for Lateral FET transistors, so most likely they were produced to be sold as FETs, and then (by mistake or on purpose ) labeled as 'TIP2955'.I contacted Mouser's customer support, and they refused to replace these transistors.I regularly place dozens of orders with Mouser every year, and this is first time I received fake goods.This is very common when buying this stuff from ***** but Mouser used to be rock solid, and I'm very disappointed with this situation.As far I know, selling fake products, especially so visibly fake, is not legal in this country, and I request a resolution to this problem.

      I created an account with this company to place an order for some parts. I paid for the order and received the parts with no problem. No issues on this end. The problem started a week later when I received an email that someone placed an order on my account. I logged onto Mouser account to check my order history. I found that Mouser linked my account with someone else who works at the same company as me. I work for a large multinational organization with over ****** employees worldwide. Included in this was personal information about the person who placed the order, including PAYMENT MEANS and PERSONAL ADDRESS. I immediately scrambled to delete all of my personal information on the account, out of fear that Mouser is sharing my personal information who god knows whom. I then called the company and asked them to rectify this immediately. I requested them to ensure my personal information is not shared on other people's accounts and to also delete the account I created. The person I spoke with on the phone was confused and after being unable to help me, I asked that they forward me to someone who would. He did not do so. It has been over a week, and I can still see personal information of other people in my account, which also has not yet been deleted. This is a breach of privacy sharing my information with people I don't know and this company still has not resolved this issue.

      I purchased the topmax iii programmer from Mouser Electronics back om 18th November 2021 invoice number 64783821.Within this time I have tried to use the programmer and have run into problems.Around the 23rd December 2021 I had contacted eetools direct from their website regards to issues trying to program a BI-POLAR PROM also an issue with a **** logic chip test function where it would fail a chip test when the chip is fine (even brand new).In this process I was asked to send a sample chips to eetools in the USA for them to investigate(at my expense) I sent samples of the hard to get chips which resulted in a software update of the maxloader(ML63e) software which appeared to correct the issue. next use the test function would fail a 74LS194 logic ic when it is ok I installed the latest software (ML63g) still reported the same chip as faulty but in another location.On March 11th Contacted eetools again once again they asked for me to send a sample chip I should not be required to send them chips to test on a programmer that they claim to support.they claim that 6 - 10week lead time for them to get part when i can order straight away from same supplier (Mouser)While waiting to resolve the second issue i came across another 3 chips with similar issue.I have contacted mouser seeking a refund but replied that unless eetools determines that unit is faulty that they will not provide a refund.I tried to escalate the issue via the Mouser website Both AU and *** website but the escalation page is currently not working. The hardware (Programmer) is not defective but the software is - as the hardware is completely dependent on the software- as a whole it cannot do the tasks that is was intended therefore DEFECTIVE.it is unreasonable to wait 2 or more weeks for the manufacturer to correct the software each time I have an issues with a "SUPPORTED DEVICE" as there has been several in a short time.
