Hyundai Service Center — axis charges received of MRP

Sir My name is Amit Goyal having hyundai i10 car since last 2 years. On 8th of sep 2013 I have taken my car to Ram Baag Service center of PL Motors Jaipur Rajasthan for scheduled service of my car. The attendant at service center advised me Injection Cleaner to clean up the fuel line (as the carbon or any waste materiel from fuel line to the engine can be clean up). The print MRP of the product is 550/- inclusive of all kind of taxes but the Service Center charged me Rs 600/- with extra taxes for the above mentioned product. I am also having the empty can and the bill of above mentioned product Injection Cleaner, If required kindly inform me on mail id [protected]@rediffmail.com i can send u the scan copy of the bill and a snap of empty can with MRP mentioned on the product to prove. Thanks Amit Goyal +91 [protected]
