Suzuki Motorcycle India Private Limited - Cheating On Two Wheeler Services

I own a Suzuki Gixxer SF **** model two wheeler. I moved from hyderabad to bangalore about * years ago and regularly I get my two wheeler serviced at Aryan Suzuki Varthur branch. In September **** i met with a minor accident and my bike had caused some damages which were repairable. I claimed the insurance on it and the total invoice amount was approximately *****/-. Since then there was some particular sound coming from my rear wheel and was not going off. I was visiting the service center for atleast once in two weeks and they did something or the other to make the sound go and it never went till date. Recently they told that there is bearing issue in the engine and they did the repairs which costed me ****/- approximately. So they slashed repairs of approximately **,***/- in total and the sound from the rear wheel still didn't go. The service center manager's name is Ayyappa and the technicians literally know nothing. They're just looting the money from our pockets and they're not doing anything. I am totally fed up with this and I request/beg you to take action against Aryan Suzuki Varthur branch. If there's any chance I would definitely tag along to show the sound coming from my rear wheel of the two wheeler as a proof.
