Mahindra can't arrange for spare parts of Scorpio

My mahindra scorpio 2011 went for a body work at concept sector 63 body shop and after two months of delays, my car is still not repaired. Its third month running and car is still in the body workshop. I have been told since last two months that chassis are not available and I am really frustrated with the delays. Because of internal inefficiencies in its internal parts procurement, it’s disappointing that mahindra makes its customers to suffer mentally and financially. Now I am left with no option but to get my car towed from the shop and discourage others from buying any mahindra vehicle in future. Body shop where car is getting repaired.
