Business ProfileforNorthwest Window & Door

I contacted NW ***************************** to replace a window and install closet doors. I let them know what I wanted, which was basically straight replacement of a window and french door style closet doors. I signed a proposal of $4561.65 for these items, which had great detail about the window, but the closet doors just had the size of the closet opening and framing info. Then, I received a call the salesman notifying me that the proposal needs to change because they need to go with a different manufacture for the window. During that call he asked if we are going with bi-fold doors and I said no that I want french-door style of doors the kind that swing out. He said okay. When I received the new proposal, it had the updated information for the window and a change to the closet door area that mentioned "Bypass double door." When they came for installation, they installed the window just fine. I went to check on the progress of the closet doors and noticed they were putting in sliding doors. I told the installers that this is not what I asked for. They stopped their work and looked at the paperwork and said this is what "bypass double door" means. After several phone calls with the salesman, he then proposed another $1516.19 to put in the french-door style door. I have no problem paying money for the installers extra-work, but paying as if this is a whole new job is not right. I admit not knowing what "bypass double door" meant and could have asked, but it is not unreasonable to ask that they should have listened to my request. I am now paying over $1500 that I should have not had too in the first place. This very much feels like bait-and-switch. Attachment shows first proposal, adjusted proposal (after window manufacture change), and proposal for new job. Open to phone call to provide further detail.
