Bad service, lack of truth in DEKRA documents- Silver Lakes GP

I am Siyabonga Ndlamla. I was in the process of buying a vehicle at We Buy Cars, Silver Lakes GP.

I paid cash via EFT, my mechanic realised that the vehicle is extremely overheating and leaking water. I requested a refund since this was never mentioned by DEKRA and it is expensive to repair that: likely cause is blown head gasket. Second problem that was not mentioned by DEKRA report is that the vehicle is sluggish and cannot go beyond 100km per hour.

I was assisted by Diago Dreyer. I paid from FNB to FNB and it is now more than 96 hours excluding Sunday and my money has not been paid. I am being sent from pillar to post. I need my money now and they must not even take a dime since theu were not honest in their deal. The manager has no people skills and he is extremely undermining.
