Hero Motocorp — Lot of fake commitment during selling a bike in showroom

I have booked hero xpulse 200 4V at southernhero showroom medavakkam, During the booking I have choosen bike colour white and blue, waited one month after one month showroom people said red colour only available sir if you need white you have to wait another 2 months, so i accepted the red colour, now they are telling it was pending with RTO APPROVAL, if you don't want wait please cancel the bike we will return amount by check, this is way of handling customer,

Already two month gone still waiting for delivery,

Already i have registered a complaint with hero they simply forwarded the complaint to showroom again the same show room people contacted and closed the ticket without delivering bike, i have paid 80 percentage of money in advance,
