These guys never give up. They call my house at least twice a month asking whether I want my Windows & Doors replaced. I told the idiots to stop calling me but they don't listen. First I told them that my windows & doors were brand new. That didn't stop them. Then they called again. This time I told them I live in a log cabin. Didn't work. After about the 100th call, I finally told them to F-off and stop calling. Yesterday they called again!.
We should start wasting THEIR time. Next time they call, tell them to send one of their reps to your house. When they arrive, tell them that you've changed your mind. See how they like it.
