Maruti Suzuki India — Performance is not good and so called mechanics are not trained

Complain against RKS Saboo Maruthi servicing Center at IDA Ramanthapur workshop My vehicle number is TS 08 EB 1945 Maruti Swift Diz. I had given my car to above work shop for general servicing and also Air bag light warning indication and also low mailage But vehicle is handed over to me with out done any work and collected labour as well as so called oil and other charges next day I had intimated/complained the same as per their promises again left my car in servicing Center for above complaints. After intimation I took my car from serving Center but they did not done any thing So I therefore request ur self pls visit above servicing Center and check and verify the trained workers are working in their servicing Center They are cheated the public. So I kindly request u to do enuiry the same. Mohan Chalicheemala
