Hero Motocorp — Hero bike service and behavior complaint

I am Rajeev Sharma purchased Hero Passion Pro from Rahul Automobiles Bariatu Road Ranchi Jharkhand on 2017. From the starting i was complaining for milage of my bike but no one rectify and resolved my complaint, today on 19th Aug. 2020 I visited to Rahul service center Karamtoli Chowk Ranchi I have given my bike for paid service at 9 am I went to service center again at 3 pm they confirmed me your bike is ready for delivery i was there for 45 minutes bike was not ready and when I ask what work has been done I have asked for paid service and there is noise in engine not body replied satisfactory they have not changed engine oil in paid service they didn't did anything except washing they wasted my 6 hours and mainly them behavior was so rude they are not talking properly is it Heros customers behavior i can't expect from esteemed co. Like Hero.

I may request you to kindly resolve my issue and ask service center persons to behav properly with the customers atleast this customers deserve.

Thanking you
