Coimbatore fed up with the ktm service, any local mechanics suggestions?

Hello all, I need recommendations for a trustworthy mechanic in Coimbatore. I recently got my bike serviced, but the experience was frustrating—delays, incomplete work, and unclear labor charges. They even billed me for a service I specifically asked them not to do. Now, less than a month later, my spark plug isn’t working, even though they claimed to have replaced it. To top it off, they still haven’t refunded the wrongly billed amount. If you know a mechanic who’s honest and does quality work, please let me know. Thanks!
