Hero Motocorp — without doing any service they charged for my bike

Address:

Madhapur Hyderabad, 500081

I had purchased a hero splendor + (I3s self-drum-cly) on 03/2018 and then given bike on service

1- given bike to service on 27/11/2019 and they said deliver time was 28/11/2019 but when we reach there they said still bike service was not done and expect me the deliver tomorrow
2-asked to check for mileage, engine oil and break shoes adjustments. None of this had be done as conformed by one of your executive who later on who checked my bike
3-asked to do for teflon polish and for that they charged me 450/- extra and did normal wax polish.
4- for above given service they charged me 1560/- for which i hope they made bill and did my bike wash and returned my bike
5- manager himself was telling to staff that i'm useless customer (While talking on phone he was telling to some other staff)

Overall this was my second time happening with the same service center in hyderabad. Now help me in understand that is this the service your team want's to give for customer or do you think that we are wasting our money

Appreciate quick response and request your team to kindly refund my money immediately, also let me know if this is the way you and your team wants to continue service then as a common man we will just shut our mouth and stop buying or recommending hero bikes to buy.
After giving complaint through online someone had called me from hero motors called me and asking me to give my bike service which was approx 50 kms from my residence place.

Imp note: don't ask me to take my bike and give it for service in same service center or any another hero service center. Because already my bike was been spoiled by the same service center earlier
