I purchased a shower door from cornerstone glass. My walls were not quite straight but the salesman told no problem, they would correct that with the measurements. The doors were put in and there was a gap when the door closed. The installers said to call the salesman and left. The salesman said the doors were not straight and there was nothing they could do. I was also threatened with a lawsuit if I did not pay the bill. Customer satisfaction - none, customer service - none. Won't buy from them again.
