Consumer Redressal

I bought a Super Splendor last Aug (13/8/13). Since Then I have complained to the Service centers every time I have gone for the servicing about the mileage from that bike. I have completed 3rd Servicing and 3000 Kms on the bike. I was told by the Service Center Reps, that the bike mileage will increase after 3rd servicing, but NOT true. I have been patient since my 2nd Servicing. But, even after the 3rd Servicing, I am currently getting 34/35 KmPL. I need to understand why this is so? And what needs to be done to get this changed? Whom should I address this concern to? The manager from AMIT HERO SERVICE contacted me and arrange to service the same and I had to leave the bike for one day. I regret to tell you that nothing has improved. It seems the bike has got the manufacturing defect. You are requested to replace the bike. P.S: I have done servicing from the authorized service centers as per the schedule provided.
