Poor service from Hyundai Boksburg

I still haven't received any feedback or communication with regards to my complaint from Hyundai Boksburg. I took my car in for repairs (faulty sunroof) on the 10th of September and am still without a car. This has caused so much distress in my life because I have received warnings at work for late coming. I aslo have to pay my neighbour to take my child to school every day. When I spoke to the manager of the dealership, I requested the use of a courtesy car since my vehicle is still under warranty. The manager was very rude to me. I have tried to contact the dealership on numerous occasions and have not received any joy regarding my car.
