four months and waiting for My car to be fixed

My car was in an accident on the 1st of December, the car was still drivable, Miway advised that I send photos of the damages and the claim was approved on the 4th of December 2014. Miway advised that Renew it Randburg will be repairing the car. I took the car through and was told that I will be informed when to bring it in, I also needed to get a courtesy car, three weeks later they were still waiting for parts and they had no courtesy car. I was told to bring in the car on the 5th of January 2015 and the parts and courtesy car will be available. Called them weekly to find out when I can bring the car in, The car only went in on the 13th of February 2015, on the 17th the car was ready, I asked if all the damage was fixed and it was not as they didnt contact Miway for approval for the rest of damage that could not be seen in the photos. I collected the car on Saturday 21 of February 2014 only to notice that the left half was sprayed a different shade of red as the rest of the car. On the Monday I noticed that the car was shaking allot when i drove it. Till now 30/03 I am still waiting for a coutesy car and when they will fix the paint and fix the mag wheel that Miway has paid for.
