Tvs Motor Company — Apache RTR 180 BSV - Battery issue

This is Saravanan from Chennai. I bought Apache RTR 180 BSV on March 18th 2022 from Sri Lakshmi TVS Motors East Avenue Korattur. I paid full cash and got the bike. But within one month, I faced battery issue (self start) in my bike. The self start was not working properly and I could not able to start my bike. Then I reached TVS Service Center in PADI. They took my bike and repaired it and handed over to me after one week. They marked it as First Service done for the bike on[protected], and the supervisor in the service center told me that he had fixed the issue by replacing the old part with the new parts. but after 10 days again I'm facing the same issue. The self start is not working and I could not able to start my bike. when I reach the service center and the Dealer (Sri Lakshmi Motors) they are not responding to my call.
