Bad customer service

I bought a Hyundai IX35 from automark in Menlyn, 2 months later the turbo wasnt charging anymore. Took it back, car stayed for 2 full weeks at the dealership. They only reset the 'check engine' light. The car gave same error 2 days later, and was told to source out an autoelectrician close to where i stay (Vanderbijlpark). Took the car to Hyundai in Vereeniging, and the car was diagnosed and same problem as Menlyn toyota was picked up. So when i contact the sales personnel whom i was communicating with, they're now playing hide and seek. Had to pay for myself, mind you, R10 000 was the quote. I am disappointed and saddened by how i was told of the "Automark" warranty.
