Kia drags its feet to assist clients

I have been complaining to Kia South Africa since last year December and no one is willing to investigate my matter and get it resolved. I received bad service from their dealers, reported it but there was still no positive response to that regard. I spoke to one of their consultants who promised to deliver but until I have heard nothing from him. My car is now a mess and I can't even drive it but still paying for it on a monthly basis. I even payed for repairs that were never done. Asked them for a technical report to see if my car had a latent defect that I should be aware of but to this date I still don't have the technical report all I have is an overheating car, with broken shift gears, electrical issues and damaged wheels. Kia head office must intervene and ensure that I get all my money back and investigate the matter further.
