Glass Surgeons of NC

Glass surgeons come out 2 fix a small stone crack in my window. After it was fixed I went home, the next morning the dent was know a crack. Then I called them and ask to replace window (because on the bottom of the receipt it says "stone cracks guaranteed for 5 years". glass surgeons said that there was nothing they could do and would not fix. I would not deal with this company they don't stand buy there work find, someone else.
