Hero Motocorp — about hero duet servicing at super auto, tarakeshwar, hooghly, w. b

Hooghly, West Bengal

I've serviced my hero duet two times at super auto tarakeshwar. Every time only washing has done properly but problem in bike is still. My home distance is 13kms from servicing point. Have i any value of time and cost of petrol? Breakshoe is to much tight after servicing. The bike sound like flute and vibrated during running. I said these problems before service but no result. My bike is less than 2 yrs old. Buying date is 30/12/2018. I need the proper steps.
