VW Hatfield's (Pretoria) worst employee

My car went in for service on the 24 May and I am still dealing with this messy services from Franco Van Eeden. My car was involved in an accident at the dealership premises, i was not informed as my took the car in for me. I had to call Franco and ask him what happened to my car and he said it was a small scratch, which was actually a cracked front bumper that had to be replaced (de-depreciated the value of my vehicle).

Eventually my car went to the panel-beater to fix the bumper and came back with an engine light on, then Franco told me to take the car back to the dealer again for the 3rd time obviously with no regard to the expenses involved (petrol and tolls) and I bought to Franco's attention that the panel-beater did a poor job on the vehicle and the right hand-side of the bumper was loose, as usual he said I must bring the car in AGAIN! at my own expense and said the front bumper was not fixed properly because I was involved in an accident a couple of years ago(which resulted in the drivers door being replaced).

I am so tired of dealing with this issue, do I go to the ombudsman or get a lawyer cause honestly depreciation of the vehicle, somewhat ***ist/****** attitude.
