Bad service Discovery insure

How much more do I need to endure with Discovery insure? I have been without my vehicle since the 14th March, the latest communication from the panel beaters, is that it's in the repair process, and the next stage of the process. I totally understand the processes, although my nightmare with the insurers continues, with calls not being returned, and who is responsible in the organization to make sure the processes are handled quickly and efficiently? Without unnecessary delays and empty promises. I have had to pay more now relying on other means of transport and lost revenue. My installments for insurance still need to be paid. Despite the fact that I don't have use of the vehicle. The date today is the 2nd May, I've come to realize that with Discovery you're just one of their millions of numbers on their income list.

Really annoyed.
