Very unhappy with the service of this Branch

I bought my 1st car with Auto Pedigree Nelspruit on 26 January 2016..In March I took my car for the 60 000km service at Hyundai. I was given a report by the mechanic of things that is wrong on my vehicle. Gearbox has a oil leak..vehicle has accident damage Rside inner cv boot has been beaten out .. L/side cv boot is secured with tie straps. The sump and exhaust is bent and damaged. Front bumper is badly repaired. Clutch needs to be replaced. I have complained about this at the manager and even 3 times at the Regional manager .. the is still noting done about this. I had a accident with this car on Tuesday on my way to Auto Pedigree. I do not know what to do about this anymore. this is unacceptable.
