Tata Motors — Poor service and Damage

Dear Concern,
I have given my car in TATA MOTORS SERVICE CENTRE for some technical issues at RAJKOT. The name of service centre was AMIRAJ MOTORS.
They have cost me rs. 40000 for first time and again some issues occurred and theu charged me 11000 for some other fault.

The fault was Created by their labour's Fault. They denied me to reimburse the expense bare by me due to their damage. They even did not give me original invoice for any such service provided by them.

When i went to take my vehicle from their service station. They have made me waited for 3 hours.

I really need help from you now. You are the last hope for me.
