Hero Motocorp — not received my prize, gold coin, won on the purchase of new bike

Address:

C/O Dr. O prakash Singh near near Seventh day School luxman puri Colony Barabanki, 225001

Hi,
This is to inform you i have purchased a new super splendor on 22nd april 2019 from a hero showroom in barabanki up. On this purchase i managed to win a gold coin, but i still haven't received the coin.
Every time i call or visit the showroom only reply i get that the concerned person is not available in the showroom right now, and they ask me to visit the showroom on some other day. The same story is going on and on for the last 3 months.
I can't visit the showroom everyday since i am also working.
Please see if you can help me with this.

Regards

Shashank vikram singh
