Poor Service, No Value for Money

Took the Mazda Drifter 2500TD bakkie which smoking to them, they said they must first do the diagnosis @ R900, and the car must be left with them for the whole day. The car was left with them the whole day as requested and afterwards they only gave me an invoice of R900, no diagnosis report , nothing. When I enquired about it , that I need a report to show what is wrong with the car and a qoute showing how much to repair the problem. The guy called Kennet stopped responding to my emails and never responded to my emails. I guess I paid R900 to park the car at their yard. Go to them if you want to pay for nothing. ********.
