I was getting calls from a home improvement company. They had talked to DH once and we were actually in the market for a new roof, so he said come on out. The guy was very high pressure and quoted a price more than twice as high as another local company. I wound up doing the roof myself, but they kept calling every few months. I told them I did not appreciate the high price, high pressure sales techniques.
Finally I told them if they were the last company on earth, I would not do business with them. They stopped calling after that.
