Shocking service

I have been driving around with 2 chips on my windscreen - numerous calls to Glasfit and I am being fobbed off by being told that "someone" will call me. Spoke to a Mr Jacobs who promised to be here on Wednesday just after 11am. It is Thursday after 1pm and no one bothered to even give me a courtesy call. Glasfit WILL accept liability for the excess I will be forced to pay should the windscreen crack as I have given them ample opportunity to do so. Such shoddy attitutes I have not come across before - shocking!!!
