Disgusting service with Maxicare

Where do you start with a company that has DISGUSTING service. My TV stopped working, the TV repair people came to collect the TV on 21/08/2015 after about two weeks I inquired about the repairs and was told that the very next day after the collection they did give feedback to Maxicare that it cannot be repaired. Now I have to follow this up and after numerous phone calls I was sent documents to sign for Agreement to Loss, to this day I have heard NOTHING. A supervisor did phone me and promised me it will be sorted out but I'm still waiting. I made numerous calls to have the supervisor to phone me back (was told they in meetings till 9, I wonder ), STILL WAITING. Since last year and this year I made numerous request for them to send me a copy of my policy STILL WAITING STILL WAITING STILL WAITING !!
