BAJAJ PULSAR 150CC
Servicing is bad in authorised Service centres

I purchased my vehicle in last 29 Jan. I've completed 6800 Kms. Last week i went to Bajaj Authorised Service centre (Pupular Bajaj, Koramangale, Bangalore) to service. This is my sixth and second paid service. I got Fourcomplaints. Rear Break is not working properly, Vehicle automatically turns off, rear wheel's air automatically go off within a hour or two, self start is not working. But after servicing they had changed my break drum, water washed my vechicle, oil changed, etc. Still I've problem. Still Vehicle automatically turns off, rear wheel with same problem.
