Atec Home Improvements - Windows, doors and other junk. I asked for windows and siding info more than 2 years ago just to see what I would save if I did it myself. It may have been via a free windows or siding drawing or someting. An appointment was made, but the sales rep never showed up. When they called to re-schedule, I told them I was no longer interested. That was over 2 years ago. Wintertime - no calls from them. Spring, summer and fall, I would receive at least 2 calls a month and as many as one call a week from these bozos. Yet, they call, and they never leave a message.
