Which Indian automotive firm have good customer care service and worst customer care service?

Let me know the customer care reviews of Automotive Firms.

I donno customer care number of any automobile company as if had any problem with my vehicle then I simply visit company service station nearby.. usually you never face any problem in a vehicle which can be reactified over phone. Secondly, whatever I drive, I am usually well aware about it so never required any phone help.

However if anyone ever used any phone number of Customer care of a company then do share here.

Rolls royce?

BTW,i am driving TATA for a file, and cutomer care is nice.

I thing Tata Motors.
