POOR CUSTOMER SERVICE

I bought a tata bakkie in February 2014. On 400km on the clock of a brand new Tata Super ace bakkie, the engine overheated. The service centeres could never find the problem. It was towed in 3 times in this year. the last time was June of this year. It was with the service centre for 2 months. This is a vbusiness vehicle and I had to phone and beg everyday for feedback. 2 Weeks ago the turbo pipe burst. When I took it in, alll of a sudden I had no warranty anymmore. I get no further response or feedback from client services.
