AAA Quality Garage Doors

I called this company on a Monday to get a quote for a garage door installation. Their price was the lowest by $100. I set an appointment for Thursday. After taking the day off of work for the installation, I received a call on Thursday morning from the contractor. He asked about the door I bought. When I told him the brand name he said he doesn't install those doors because they're junk and difficult to install. I asked him what he would charge me to go ahead and install the door. He said he would do it for 4-5 times his original quote. The very next place I called told me they would happily install that brand of door for about $100 over what this guy originally quoted. By the way, the brand of garage door is a highly rated national brand. A google search turned up no complaints about this brand of door.
