Hero Motocorp — dealer cheating

Address:

Rewari, Haryana, 123106

I bought a hero duet on 11 march'18 from niraj automobile dharuhera, i paid all my money including rto number plate but after four months i didn't received number plate. Everytime i'm getting different-different excuse. It's a risk for me to travelling on road because traffic police will anytime charge me for number plates. Please look into this matter and take a action against dealer.
