PG Glass Table View - Poor Service and Disappointing Customer Care

My wife was victim to a smash and grab on Monday and PG Glass Table View does not carry stock of the front passenger window for immediate replacement. Understood, so the temporary solution is to install a temporary cover, which eventually gets done late on Tuesday. While travelling on the R27 the temporary cover blows out and could have injured someone on the side of the road. My wife call PG Glass and reports it. No apology, no urgency to repair and eventually my wife has to call PG Glass back on Thursday to find out what is happening. Then she has to drive in to PG Glass Table View where the staff believe it is a joke by actually laughing off the situation. I don't know if PG Glass has the monopoly in this industry but I would urge Discovery Insure to have alternative and more competent and responsive service providers for its customers to use in situations like these. We are very frustrated with PG Glass and this unprofessional behaviour.
