Yamaha Motor India — Extortion of money in name of repairs

This complaint is against Rudra Automobiles (an authorized service center and distributor in Belurmath, Howrah, West Bengal). My bike displayed a starting issue, so I took it to them. They informed me that the problem was with the battery, which they replaced. However, the issue persisted. Then, they claimed the problem was with the charger and replaced my perfectly functioning charger. Despite this, the issue continued. I returned to them again, and they kept my bike for over a week. Even after that, the problem remains unresolved. I have spent more than ₹5, 000 on repairs, yet the issue persists. Furthermore, my salary was deducted because I couldn't go to work without my bike. I now seek a resolution to the issue, as well as a refund with interest for the loss and harassment I have endured over the past 6-7 months.
