Dad experience

I'm every disappointed of the experience I'm getting from your hyde park branch . I have been a GM customer for two years now. Have had my car serviced by you guys. And last year the was something wrong with my car took it in. The car was sorted in no time and I was very happy. Things changed this year now I haven't had my car in almost a month .It got bumped by one of they're drivers at the workshop while waiting to be fixed a machenical problem I had with it. I was given a car to get around while they fix the bumper. And was told that might take two weeks I am still waiting for my car on top of it all I'm expected to pay R25 per day for the car I was given by them to use in the mean time. It's about R900 now since its been almost a month of having this car. Now I'm being charged for something that was not my fault to begin with. I'm Frustrated and Annoyed by this.
