POOR CLIENT SERVICE FROM GWM SA

I am the owner of a 2011 GWM. End 2014 there was a problem. Lights on the instrument panel going on and off. The vehicle taken to the service centre and problem reported. 2 days and almost R 7000.00 later got the car back and assured all was well. 22 December 2014 car broke down and was taken back on the 23rd. I tested battery and requested that alternator be tested. Car released on the same day with report that there is nothing wrong. 24/12 the car broke down again. Various calls to GWM and no response - whole festive season stranded without transport. 27/12 car towed to GWM. Collected 29/12 told loose wire and fixed. 19/01/15 car broke down. Reported to GWM with no response. Car towed at my cost again. Then informed it is the alternator and had to pay a further R3500.00 for the repair. Reported to GWM SA - no response after acknowledgement of receipt. Demanded feedback and reimbur*****t of the expenses incurred as result of poor service. No response or feedback.
