PG Glass Incompetence

My wife organised with you to have her windshield replaced at our home at 15:00 today. Your technician was at the house shortly after 12:00. I was called, not my wife. I sent him to her work, but as she is a teacher, she was not able to get them to her car. They left. I phoned in to get them to stick to the 15:00 appointment. I was told the technician would call me to confirm. My wife (not me) was then contacted at 14:00 to say it has to be done now as there are no alternatives. So now she has to change her whole schedule to accommodate your technicians who are unable to follow any kind of schedule or even do the things that they say they will. This whole process has been a horrible display of incompetence on your behalf.
