Royal Enfield — not on time delivery of royal enfield thunderbird 350 x bike

Address:	110048
Website:	www.southdelhimotorcycles.com

I had booked royal enfield 350 x on[protected] from south delhi motarcycles, address: kailash colony new delhi 110048.
At the time of booking they confirmed me delivery date on[protected].
Its more than 15 days from the confirmed delivery date and i have not recieved my bike.
Whenever i call them for delivery date, they post pone the date, and if i question them them harass me saying u can take your booking amount back.
Moreover they have pathetic customer care, they have never called me for informing me anything, its only me who calls them and takes update. Plus they are so reluctant to answer calls, so i have to call them from diffrent numbers everytime.
