Sorry this is long but this is as shortened as I can get it. We entered into a contract 4/1/21 with a window installation company to replace all of our windows. The windows arrive to be installed in August 2021, but half of them did not fit so they had to be reordered.  In addition to them not fitting we question the actual workmanship of the window sashes. The welding was bad, there was plastic that was cut in certain spots that was sharp on handles, there were gaps, there was many issues with the actual quality of the product. Over the course of the next 6 to 7 months the company came to install the windows that have been ordered only to find out that windows have been ordered the wrong size again. I think we had a total of five or six service visits where they attempted to install windows, they did not fit, and none of the windows were still fitting.  When they came to install the windows at the second service appointment they actually took all of our old windows out,  so even the sashes that did not fit were left despite the fact that there were gaps and areas visible to the outdoors because they were so small. They attempted to fix it with blue painters, tape around all of the edges of our windows for months because they could not get the measurements correct.  Things became so out of hand that in December 2021 we met with the regional manager who came from Ohio to our home in Michigan to look at the windows where he agreed the quality of the product and the lack of correct sizes were so bad he agreed to re-order every single sash for every single window and promised they would be fully inspected for quality inn size before they left the factory.  We attempted to communicate with them for the next few months wondering where her windows were and then we were finally told in the middle of March they had arrived and were inspected and a service man came on March 15 to install them and guess what they didn’t fit. At  that point we continue to question if it could be the actual frames because the installation on the very first attempt did not go so well because they did things very poorly so we are wondering if maybe the frames themselves were wrong.  On March 15. The manager said he would figure out what he would do next and let us know. We did not hear back from him so we contacted another manager who told us to please make a list of everything that still needed to be done, which we did and we sent to them on March 23, 2022. He was a Google Docs so we have verification they did view it.  We have not heard from them since.  We attempted to reach out to them numerous times, and all of our text messages, phone calls and emails went unanswered.    In our contract at stated that we would pay upon completion of the job. Our contract did state the job would be completed within 1 to 5 business days after it started and we gave them grace on that, but after 2 months of not hearing from them we called an attorney who told us to just wait for them to call us because they are the ones breaching the contract with walking away from the job.  two days ago we received a letter in the mail, 12 months after they stopped all forms of communication with us, demanding we sign a completion form and pay $13,000. The letter also stated at the completion of the job was March 14, 2023. They have not spoken to us since March 23, 2022. Due to issues that we had at the beginning of the process with them I documented everything, videos, photos, emails, and I even have signed documentation from service workers about things that are wrong.  The demand letter states that they are to receive the signed completion form, which was not even included in the package they sent, and the payment by March 28, 2023.  to keep things in writing I emailed the lady who sent the letter and sent her the document we sent and 2022 with the items not done and  All she did was tell me she was going to send it on to another manager. I requested a phone call back, that was Thursday, and I never received one. I spent hours Thursday, trying to talk to attorneys, which nobody ever returned my call and I filed complaints with LARA, Michigan Atty General, Indiana Atty General (where the business is out of), and BBB. However, with a deadline of only a few days, there is no way that anything will get accomplished before Tuesday. However, I do know that they did receive the Better Business Bureau complaint and the complaint from the Indiana attorney generals office. Michigan’s  attorney general told me that somebody would be able to pick up this complaint on Monday and hopefully reach out to the business on Monday, so hopefully that does happen. Nobody seems to be able to tell me legally what my rights are! The demand letter also threatened that if payment was not made by March 28, they would put a lien on my home, send me to collections, and a few other things. Not only did they walk away from the project, but they left us with windows that do not fit.
