Hero Motocorp — Service center not providing good service

Address:

Indore, Madhya Pradesh

The service center of quality showroom bengali square indore is not providing a good service.
My bike hero maestro was serviced second time on 2nd fab.2016. After that i faced many problems including low mileage majorly.
When i went for 3rd service on 5th of may then on the mileage issue the service provider says that they could not do for that.
In addition to this they ripped off the next service page saying that my 3rd service date has been over.
Should i file a complaint to consumer forum...?
Please give your reaction to this.
