So I got a flyer in the mail from meridian doors and windows. Said free upgrade to triple pane glass or 25% off windows for double pane and that they offered financing. So I decided to call them cuz I was in need of new windows, patio door and decided on a front door as well as a spur of the moment thing when the quote guy was in. So after he finished his quote, we went with the financing and was told everything was included in it. And boy was he wrong. First there product is pretty good. And installers where great, but that's all that was good. We where told 6 to 7 weeks for delivery for install, that turned out to 3 months for the patio door and front door, the 3 windows that were suppose to be installed where the wrong size. And their office was telling them to cut apart my walls to make then work. Thankfully the installers told me and they themselves refused to do it. So I had to wait another 3 months for the new windows and finally where installed in October. 7 months after the day I had the quote done. And now I have them phoning me to pay for the front door that was suppose to be included in the financing (which was handled by meridian) but they did not include it even tho it's marked off on the paperwork that it would be. Now I understand their side of it as I work in a industry that involves a lot of quoting and pricing but I have never seen this. First they phoned to say they screwed up and that I needed to pay them. And I explaned my side. Then I got another call to tell me I ether come up with solution to pay of they take legal action. Now my side is that I was told it be all financed or I wouldn't have the door installed. They never mentioned in those 7 months that it was never included into the financing, actually it was never mentioned at all. Now they told me today that they were not able to included the door into it because of financing limit. Which I was never told otherwise it wouldn't have been installed. But they put it in anyway and never said anything or said anything about it being separate from the quote. Aka a second quote and I didn't notice as I was told it was all in one and it would all be financed. Long story short there expecting payment ( which is understandable to a point). For there screw up, 3 months after everything was supposedly dealt with and and everything with this company was a mess. In my industry I work in if someone screws up like this the company takes the hit because things like this screw everything for people.
