Failure to respond cracked windscreen claim.

I have lodged a claim for my BMW windscreen replacement during Feb 22. The services I received was very very poor. The claims specialist Ashraf Hoosain is very useless. He refused to talk to me on the phone and asked that I should send an email which he will forward to his manager. I sent many emails and met with silence. On the emails, I asked a simple question why original BMW windscreen cannot be approved, no one bothers to respond my emails. I will not recommend anyone to join auto and general, they are useless insurance.
