Worst car and Worst service!

Worst car and Worst service!

Myself Tushar Patel from Ahmedabad, Gujarat. I had purchased Mahindra Quanto model C-8vehicle in 23-OCT-2012, from "Punjab Automobiles (India) Private Limited". I have always given this car for service on regular basis. Before that, I had a Maruti Wagon R and used till 4 yrs and sold it. So, no chance about my driving skills. In Nov-2014, I had an issue with the car and gave to Punjab Automobiles and they said having issue in engine???? Wow, I think all car segments having an Indicator alert before when any issue arises in the engine but this car never and we had no choice at that time. I had also asked for the warranty, but it's already expired and I asked service manager to repair engine and solve all issues and then ask for warranty for 2 yrs for engine but at that time they said why do you want to extend, after repairing the engine, we will give 6 months warranty. After 6 months, you can extend it, no need for now. Now what happens, my car also have an issue like water leakage issue from the radiator. This issue we already faced when the engine had an issue. So I asked for warranty before 6 months completion so now they are not agreed to give extended warranty. So now I am afraid for this car again. To avoid confusion, I was thinking to show this car to the different service center for a better solution. So for diagnosis, I binged my car to "Sheetal Motors" at 25 July 2015 and they said in your car have a radiator issue, you have to change it. But I have already changed the radiator on 19-Jan-2014 but again the same issue. So I again went to Punjab Automobiles and those guys said, the car radiator is okay but heating coils have an issue, so you need to change that and charges will be around 12,000 INR. Wow! what rubbish things are going on???? What I have to do??? Who is correct, Sheetal Motors or Punjab Automobiles??? There are only 2 service centers in my city. So I am really confused about it. Seriously this car gave me too much headache, nobody answers to me even when I ask customer care but never get any single reply.  So please do not buy Mahindra's car.
