Worst service experience from Hyundai boksburg

Took my vehicle for service, received a call at about 15:00 that the vehicle was ready for collection, arrived about 30min later to find out that there is only one service advisor available and that's all the branch had. Waited 1h30m while she tried her best to assist all in the queue. When I finally got assistance, I noticed there was a dent on my bonnet which was not there earlier in the morning, I had to go back and enquire from the help desk and was referred to the workshop foreman who came to inspect and wanted to tackle chances by saying the debt was there when the vehicle came in. He started mummuring when I asked for the CCTV footage to check if nothing was dropped on my vehicle during the service and promised to give me a call the next day. No call came through from them, they keep diking and diving. All they want is their money and that's the end of it. I am never Taking my vehicle back to that place all I want from them is to stamp the service book which they forgot to do as well.
