Bad customer service!

I took in my car for repairs to Superbody in Cape Town, on advi*****t from Outsurance. The panelbeater estimated 8 days repairs from last week Tuesday. I have to call the panelbeaters this whole week to get some feedback as to how far my car is, only then I would receive updates regarding my car. I called & sent email to my Claim Advisor to assist and she was not available. I called Superbody today, to be told that my car is still in panelbeating and it is not ready today!!! At no point this week did Superbody call me to say there were delays and would not complete the car by today, the 8th day. When I call Outsurance, the Client Service Consultant Maureen is defensive and tells me that I will not get a courtesy car from them and that Superbody merely estimated and basically there is nothing they can do! What I keep repeating is that why did Superbody not call to say, the car will no longer take 8 days so that I can plan my life! I am Outsurance client and surely they should intervene when Im not satisfied with their supplier! I am besides myself with disappointment and ready to cancel my cover with Outsurance! This is ridiculous! Why am I paying a premium with Outsurance?!
