Two weeks and still my claim has not been completed - a simple windscreen replacement

glass claim # ********** - two weeks later and I still have a cracked windscreen. The guys came last week thursday to install a new one - they chipped the paint on my car and the windscreen cracked when it was put in - I was assured the latest they would be back was monday by Jan as the cracked windscreen was not safe to drive around with. Have heard nothing back. Terrible service and my excess is so high - think it is time to shop around again
