Frustrated Customer due to repairs taking forever

I would like to convey my disappointment in the way my claim is being handled. I logged a claim with Miway on the 15th April 2015. I mentioned that I will need that this claim be handled as soon as it can be, looking that I have a rented car that Miway has arranged for me as part of the benefit that I have on my policy and I was promised that they will do their best. I followed up with the panelbeater who is allocated to fix my car and to my surprise the panelbeater has not even started to work on my car. I am so frustrated at the moment because I have to return the rented car tomorrow and my car is still waiting for authorisation of some extras which the assessor did not quote for according to the panelbeater and this is delaying the repairs on my car. I sent Miway an e-mail yesterday and to date no one came back to me with a response. This is really an appalling service I am receiving from Miway and I wonder if Miway know what the Voice Of the Customer is. PLEASE CAN SOMEBODY LISTEN or Your Way at Miway is to ignore us?
