Refuse to repair my car

On the 29 September 2015, I took my car in for a service at Hyundai The glen. As I was driving in the yard one of the employees( Interns) reversed into my car and bumped me on the right rear. I reported this immediately to their supervisor who advised me that they will repair the dent. He said I should take the car to the Dent doctor few meters from them and get a quote. I did that and received a quote. He told me that they will contact me once the quote has been approved. Weeks went by without hearing anything from them. I then called the and he said that he will contact me back. He has been taking me from pillar to post. I spoke to his manager Danie who said that he knows nothing about the incident and that I should report to my insurance. Now tell me which insurance will pay 5 months later? I am appalled by the way in which they handled the matter. I will never take my car to The glen for a service again, and have advised my friends not to either.
