Lack of customer care and inefficient service from Miway and Impact panel Beaters

I am frustrated, irate and disappointed in Miway and Impact Panel Beaters. It is now 3 weeks that my claim was approved by Miway and my car sent to Impact Panel Beaters. When I followed up today i was told that they are still waiting for car parts and that it will take another 2 weeks for them to be delivered. This would have taken my car a whopping 6 weeks to get repaired. There is lack of communication from both parties. I have been with Miway for 6 years, never claimed for an accident, and today they cannot even offer me a courtesy vehicle for the inconvenience they and their service provider are causing me. I have no means of transport. I am stranded. Miway does not even care!
