Additional Notes

Complaint: On June 28, 2013 I signed a contract with NexGen Exteriors to have them install several thousand dollars worth of windows in our home's basement. I gave them a check for over $2000.00 and have not heard from them since. Except for the times I have repeatedly attempted to contact. The only call they gave me was when I flamed NexGen Exteriors on Marvin Windows Infinity's website. They called me the next day and said that they understood that it had been weeks since the delivery date has passed but they would get to me as soon as possible. Well, now it is later and still I have heard nothing. Today I called the Campbell County Sheriff's office to file a complaint of fraud, in that they took my money and have not done anything like a normal business would be expected to do after receiving several thousand dollars toward a purchase. They Sheriff's office gave me several options and this is where I am starting, with the Better Business Bureau.

Desired Settlement: What I want, is to have all my money refunded and never see Marvin windows or NexGen Exteriors ever again.

Business Response: We did receive the letter about the complaint and I did try to make a response on the BBB website but I wasn't sure that it has posted to our page. We also made attempts to stop by the BBB office in person to discuss the situation but it was closed. I believe that Mr. ******* had made the complaint against us because there were broken lines of communication in the installation scheduling. We had received a couple messages from him asking when the installation would take place. We returned the call notifying him that the windows were in and we were preparing the stain finishing process before we would install the windows. The actual installation date was about a week after he had made the complaint. Since we have completed the project Mr. ******* has been very pleased with the final outcome and has paid us in full. We did not know that he had made a complaint during the final completion of his project it was only several weeks after that we received the letter from the BBB when we found out. We have spoken with Mr. ******* about the situation and mentioned that we had left messages with him throughout the process on his cell and home phone. He did admit that he never checks the home phone messages and he works long hours in a coal mine and does not have access to his phone. It is our goal to provide a quality product and installation for our consumers. There are several factors that can extend our lead times based on manufacture delays, scheduling jobs for the amount of crews we have, staining and finishing options. We put so much focus on the quality of the finished product and want our customers to know that they got what they paid for and not to rush through and deal with the consequences of "lack of quality" down the road. We are a growing business and are working hard to accommodate the communication process to our customers. 

It has never been and never will be our intent to provide inadequate service in our industry. We value the opportunity that we have and do not want to deface our image in any way. Since we have been a member of the BBB we have never had any issues and the fact that we have had two so close together disturbs me. I would like to speak with you personally so that we may work together in handling these situations properly and more efficient.

Consumer Response: Better Business Bureau:

The windows are installed.  The lines of communication between the installation department and the sales department at Nex-Gen seem to need improvement.  I did call Nex-Gen several times and it seems that a response happened shortly after posting my initial comments on the BBB website.  

One of the most problematic portions of the transaction seems that the sales department stated that the windows would be installed within six to eight weeks, the contract stated eight to ten weeks and the actual installation took 13 weeks.  I understand if a company has quite a bit of work scheduled but I do expect a timely response to expected installation.  I can order something from a vendor at my place of employment and I can find out anytime during the process the expected date of delivery, be it short or long.  That was not the case with Nex-Gen and that is my biggest complaint.

In the future, if I choose to deal with Nex-Gen, there will be written into the contract a penalty amount in regards to installation expectations including expected timelines.

The windows do look good.  The different hardware for the same windows was unexpected but at least the windows are in different rooms so it is not as easy to notice by others.
