They are RELENTLESS, calling at least every other day. At first we tried answering and telling them we're not interested, but they keep calling anyway. We made the mistake over the summer of allowing a salesman to come give us an estimate. He quoted us at over $15,000 for windows just on the second floor of our house. He could see that I was stunned at the number, as we had done our own downstairs for a fraction of that price. He continued with his pitch anyway insisting that we could finance and pay $350-$400 a month. The sample window he showed was nice, but not nearly worth the price. we didn't have any specialty windows, just basic replacement windows. But anyway, they just keep calling and calling, my patience has worn thin, I can't keep telling them no thank you, so I just let the machine pick up every time now.
