Indica Xeta: The Horrible Card

Hi,
I'd purchased tata indica (xeta) 2 years back. From the day I purchased this car, my life become hell.
My xeta suddenly stops taking the pickup. I'd gone to every damn authorised dealer of tata but all of them serviced the car. After servicing it goes fine for 1K - 2K and then again starts showing the same problem. In the last servicing I'd given the bill of Rs 7000 for bill and given the assurance that it will work fine now.
There are so many others problems which I'm facing like:
Low Milaege
Very poor Service Centres
No one wants to take the call
Bad Quality of Interiors

Please help me out.
