Tata Motors — vehicle not serviced, one spare part to be changed

Respected sir,
Myself ranjeet singh bal owner of bal frieght carrier & vehicle no:nl018381 hereby writes this letter complainig you about my vehicle not been checked. There was assurance given by tata motors that my vehicle 's one part would be repaired as there was leakage in that... But there has been 2-3 days since there was no response from you, after several try only one worker is doing upon that & in this case it would take many days as i have to deliver my product at the next company also!! Your this service to customers is really very poor, there has 20 yrs since i have been your customer & you expect your customers to be joined with you ahead after this service. I am extremely sorry but you service isn't such fast. My vehicle nl018381 is standing in bafna motors... Plzzz do look after my problem & solve as fast as it is possible. Sorry for inconvenience.
Thanking you
Bal frieght carrier
