Hero Motocorp — I am complaining about the service and insurance claim

Address:

P10 Taratala road opp-taratala sbstc garrage kolkata 700088, Kolkata, West Bengal, 700088

My self Shabnam Ara from kolkata.
Every time i am facing the same problem about servicing and insurance claim in kolkata, taratalla.
I've already paid the full amount but the result is zero.
Yesterday i paid 1814 rupees service+insurance claim and the manager S. bose he told me that your vehicle is ok and i took my vehicle and went back to home but in the middle of road i am facing the problem like looking glass is not fitted properly and CABLE COMP SPDMT is not working and HEAD COVER, GREECING AND OIL FILTER, S. bose took the full amount but not give the parts properly. I will never ever bare this type of service as u are giving. Its totally worth.
Today i am here in service center in kolkata, taratalla and the manager is not here, one washing boy his name is Vijesh, told me that yesterday his manager S.Bose forcefully told him to open the parts even he dont know any thing about vehicle because he is not a mechanic.
Now i am very angry...
I dont know what to do...
