Need help on Bike repair shop

Hi, I need to service Bajaj Pulsar 150. The official Bajaj service center in the city (Near to SCS hospital) doesn't seems to be helpful. The service center technician's not at all bothered about the problem which my bike has (I think they are least bothered about the bike once its sold!!) and after a multiple visit the issue not at all resolved. Is there any good bike service center's in Mangalore where I could trust and get the issue resolved.
