PATHETIC AFTER SALES SERVICE FROM DEALER

I purchased a brand new GWM H5 from the above NMI Umhlanga in April 2014. In June 2014 i found that the gearbox was faulty. I called the dealership to report the fault. My vehicle was taken in and the gearbox was replaced on the 9 July 2014. A week after collecting my vehicle the same problem had occurred and the vehicle was called in and had 2 new gearboxes fitted. 2 months later the same problem had occurred and the oil was changed and vehicle handed back to me. the problem persisted ever since and i sent my vehicle back to the dealer in July 2015. The service Manager had admitted that the transmission is faulty again. When i approached the Dealer Principle and asked him to have the vehicle replaced or refund my money, he stated that he was just the dealer and not the manufacturer. I have experienced many mechanical problems with this vehicle and therefore seeing that it was a brand new vehicle need to have this issue resolved asap.
