      0ct. 19 2025 I **** ****** initiated contact with Guardian Interlock Systems and after reviewing their offer that states clearly in the advertisments , all written and printed conference or reference material and oral staements made in communications over the phone with Guardian Interlock Sales Representitives that the services they offer Garuntee and" include free installation, free enrollment, free monitiring for the first month and NO HIDDEN FEES." so I had the Guardian Interlock Representitive schedule me an appointment for the free installation.

      The appointment was,scheduled for the following day Oct. 20 2025 for installation where i was simply given a phone number to the installer that I presumed to be from Guardian that is located in the same town. The shops name is ******* *******. After a short series of correspondence over the phone I was told that the installation would take around 2 hours to complete and after questioning a man, i found out later to go by the name of J***, about any paperwork he might need I was assured that all that was needed was,the vehicle. There was no mention of payment for the service period or any request by juan or the guardian representitive to review any documents or agreements of any kind especially concerning any out of pocket unannounced payments for what was promised to be a free
      On the way to pick up my truck I got a text that said " that'll be 200$" and after responding that i had never agreed to any payment or had seen or signed any documents,or entered into any agreements to that effect the man refused to give my keys back until I paid.
      I called guardian and they told me to pay him and they would credit my account which I refuse to do considering that its exthortion by a third party that i was directed toby guardian and never have or ever wanted or signed any contract. ******* ******* has unlawfully possessed my vehicle for 5 days now and Guardian Interlock hasnt done anything to resolve the theft.

      We greatly apologize for the interaction with our third-party contractor and their failure to adhere to our contract. We reached out to Mr. ****** today via phone and email to find out if the shop is still in possession of his vehicle. If it is, we should be able to work this out between our field management and the shop directly to release his vehicle with or without the interlock and no payment. Whichever Mr. ****** prefers, we'll do, but we need to hear back from him to move forward.

      Client #: ***********/ Invoice #****—It is tough to speak with anyone. You have to wait 30-45 minutes on hold to talk to someone, and then maybe that agent knows what they are doing. I have used a guardian ignition interlock for several years and have always had the added insurance. After an accident (not my fault), I'm being told I must pay full price. **** **** **** in ***** helped me with the older billing and knows I had/have the extra insurance or at least be grandfathered in for having it on the new system. Please help me to understand why they are not honoring my insurance.

      Guardian of ***** is run by a franchise and the ********* corporate collections team mistakenly processed a loss claim on this account. We have since voided the invoice created for the replacement costs and will let the ID Guardian franchise handle this with the client directly.

      Better Business Bureau:



      I have reviewed the response made by the business in reference to complaint ID ********, and have determined that this does not resolve my complaint.  For your reference, reasons for rejection are included below.


      They tell me they are going to re-do the claim; however, they did not detail how much I'm going to be charged. What are the new charges?




      Regards,

      The party responding to this complaint is with ********* corporate and cannot advise on the ***** franchise's pricing. The client will need to continue this conversation with the ***** franchise or the complaint needs to be transferred to that franchise if the client is not satisfied with the outcome after speaking to them.

      I reached out to Guardian Interlock to have their device installed in my vehicle and was qouted a price of $87 over the phone. I agreed and went to my appointment where the device was installed, I then was presented a contract stating I would pay three times that amount ever month. I refused to sign the contract and stated I would like the device removed from my vehicle. The installer told me they could not remove the device without the permission of Guardian and that I would need to call their 1800 number. I have now called the 1800 number and sent emails repeatedly for over three months and have never received a response. I have now received a letter from guardian stating I have an outstanding balance per terms of our agreement (which I never signed) and I am responsible for the cost of the device. The letter has no balance listed or method in which to pay the balance. The only contact listed is the 1800 number that I then again called multiple times and left multiple voicemails. I have never received a response from guardian. I have now received a letter from the DMV stating my license will be revoked due to non payment to Guardian Interlock. I have never received a bill, an email, or phone call regarding any payment and am completely unable to resolve this issue due to the Guardians seemingly fraudulent business practices. I am currently in the process of speaking with attorneys on how best to handle this situation.

      We apologize for any confusion, but Mr. ***** received a special, manually adjusted rate. Our contract numbers pull from the fee group the client is assigned to, so we are unable to alter the contract to show the manual rate given to Mr. ***** on that contact. This was explained to Mr. ***** when he was emailing with one of our representatives on 9/1/23. Mr. ***** responded by saying that he wouldn't sign that contract and would be removing and disposing of our device. The representative advised she would be happy to schedule a removal appointment and advised that he would be responsible for the full cost of the device if he did not return it. Our phone records don't show Mr. ***** attempted to reach us by phone between 8/30/23 and 1/15/24 to resolve this. 

      The Guardian Resolution manager will reach out to you today to see how we can assist you.
