I would have never used their service if I had known they would harrass me with repeat sales phone calls. They continue to bombard me with sales calls years after they replaced my glass  Even after requesting that they not call, they continue to do so. This is very unprofessional in my opinion. I would not recommend them based on my experience. I have used Penske glass and had great experience with them and they have not bothered me with repeat sales calls.
