Business ProfileforExcel Windows

My main issue is we were misled by the sales team believing it was 10 years no interest and ONLY 3 months with no payment. And after the 10 years is up, it goes from $11,641 to over $16,000 JUST for some windows which is just ridiculous. I should have known salespeople JUST tell you what you WANT to hear. Telling me stuff like, "I have these exact same windows in my home, and I love them." And another example is when I called around and had other in home estimates everyone was telling me some ridiculous amount of weeks to wait, explaining to me because of covid and shortages on material and workers, HOWEVER with Excel, I was told it would be so much faster which helped push me to make a decision to choose their service over the others, but in the end I STILL ended up waiting as long as everyone else told me I was going to wait. IF I had known that, I would have never went with this company because I was told the amount of weeks it REALLY was going to take AFTER I signed the contract. Then I was also NEVER called after the windows were installed, you would think someone would stop by or call to follow up to see how install went, but nope, no call. When I called them regarding my contract and IF it was *************************************************************************************** up with, but yet the guy on the phone would rather direct me away to the financial company and give me their number to call instead. I'm sure if I called asking for them to check how much credit is available to buy more windows or doors, they'd be happy to keep me on the phone. Just so many mistakes I felt by the company and causing the customer to be misled. I just feel more people should be aware of these issues so they don't fall trap to a long term contract or be forced to pay $11+ grand in ********************************* So now we may end up tapping in savings to just pay this quicker in 90 days to avoid the 10 years and interest.
