This kind of ******** act should be stopped plz

I went there to sort out my vehicle; It had a knocking sound in the engine. As you know the bmw SMG dealership is right next to the Land Rover dealership. So I drove pass bmw heading for land Rover dealership. I saw this person who look like a machenic. I wanted to know a straight entrance to Land Rover Dealership so pointed but the he made a prosal. He told how expensive it would to fix my car there might as well sell it. But there other option for is him to assist me because he works there as a machine and knows the very well. So I thought to myself mayb that a better option. I grew to know him as Ntatheli Xaba. So he came to see what is the car's problem and stated that it was mixing. So Him(Ntatheli Xaba) and his two friends will be able to work on the engine. So they took the car to their storage place. A week passed, he called to say an amount of R6000 was needed and a week later stated another R4500 is needed because the whole engine needs to be sorted. Then a month passed no responce. I called he stated it almost done again another month passed nothing. I used my tracker app to locate my vehicle. Parts where missing along with my money. I found out that he worked for German Spec before worked for Land Rover. Machenic Ntatheli Xaba from Land Rover Durban is a ********!
