Unable to help distraught family

On and around 21:14 on 13/11/2015 standing at the traffic light on the intersection of Ssummit Road and R55 my wife in our 1 series BMW when a person approaching the passenger side of the vehicle, my son, sitting in the bask seat of the passenger side of the vehicle screamed wide of a person at the window.. Frantically she dove of in front of her at the traffic light, she accelerated across the intersection onto the R55. The perpetrator broke the pass anger side glass. My wife, son and daughter was distraught, She tried to get my attention and pulled of onto the side of the road a couple of times. Discovery insure called me, unaware of what was going on, I told the consultant that my wife is driving the 1 series BMW and that she was behind me. Unaware she got back and continued driving. She drove to the Zenex garage at Crowthorne and called me informing me of the incident. I immediately turned back and went to the Zenex garage. I called Discovery insure to learn that they are unable to assist from Friday until Monday to sort the broken window, inform me that I have to charge my credit caruntil Monday. I found this unacceptable as they are unable to resolve the matter swiftly....
