Non approved windscreen

Unprofessional and **********. A non approved glass was fitted onto my BMW. I picked it up through my dealership and contacted Auto and General last week Monday. My glass has still not been replaced and I have not been contacted by Auto and General or the Supplier even though I have called in so many times and escalated the matter. Your company has been allowing Glassfit to install non approved parts into my car and obviously many others. This is ********** and against the consumer act. I solely blame Auto and General as they are my insurance company and were meant to be in control of this. Seems like a cost saving act from Auto and General. I would like use Social Media to ask your clients to check their windscreens and know what they are dealing with.
