Worse service from Daly Ford Klerksdorp

Bought my grandson a Ford KA. Took it to Daly Ford in Klerksdorp to go through it. They send me a quotation for things that had to be fixed. I mentioned to the workshop manager that it had a oil leak. He said they would check the car. After R9500 i got the car back. Dirty and with still the oil leak. I contacted the manager and he said i should take the car back to them. After two days he send me a photo showing that their were no leaks. I felt bad because my paving had oil on and the pipe under the engine were wet with oil. I went and fetched the car. With shock i saw the oil on my paving and found that the same leak were still there. I contacted the manager and he just said that the car must be a ghost.
