Why not to claim with Momentum

I work from 7-16:00 daily.<br> <br> I phoned to claim to fix my car door, the lady said I can book for 8AM on Monday morning to have an assessment done. The assessor did not pitch up for work, so, there was no one to assess my car. There I am stuck in traffic after being told that the photos the man took will be sent to Momentum. Then I get a phone call: 1) They call me sir, when my name clearly states I am NOT! 2) They have the wrong surname, I have NEVER had my surname changed 3) My ONLY options are to either go back there and sit and wait for Mr assessor to pitch up or cancel my claim. Then I was told that I would get a call back in 10min (yesterday) and I didn't receive one, just to be told they tried... ONCE today and didn't even leave a voice message for me to know that it's them.<br> <br> Why do I not want to cancel my claim? In 2011 my car window was smashed by one of the guys next to the road mowing the lawn (for the city of Jhb). Then I waited 6 weeks for authorisation only to fix the window myself and then they still kept the claim. <br> <br> Now that I have complained to them, all of a sudden my authorisation is through.
