Mahindra service departent, Menlyn

I bought this beautiful car beginning of 2013 Mahindra XUV W8 500.<br> The problem started early 30 000 Km. I send my car in for a service, and ask the service department at Menlyn (old one )where I bought it, to please change the right front globe on the car. When I drove Out that day, the brake lights didn't work. Drove back, ask to please check problem. They said they cant. They said something wrong with the wiring. They told me to go to silverton Mahindra, car was there for 2 weeks. Car was fine afterwards, Then the headlights globes startered to blown, changed up to date 37 globes utd. Beginning of the year, aircon only works when I hit the dash board, signal lights came on that tires were flat, buts is not. My radio FM signal doesn't work. Must say Management did try their best, but looks like there is not a proper appointed individual there that really knows what going on. My car was in for its 100 000 km service and to fix everything after I waited for parts for the last month. Last week 14th and 15th of May2015. They said everything are fixed except the radio. Well everything else still the same when I drove out. My sons Notepad which he left in the car accidently also ******
