Renault TRYING TO CHEAT INDIAN CUSTOMERS!!!

I had booked one of the Renault cars Duster in July with Renault's Kolkata dealer against Booking ref No is 238 & had paid a booking amount of Rs.50,000. The dealer promised the delivery to be done within 30 days. Initially, we were told t hat the vehicle will be delivered during Aug'12 later on promised for September'2012 delivery rescheduled to October'2012 and to my utter surprise now they are saying that the delivery will not be possible before Feb'13 and it might take Mar-Apr'2013. They are forcing to accept either of the option to pay more for the upper version or else wait till Feb-Mar'13. It is very difficult to believe the system failure on the part of a century old European organization like Renault with their customer. Renault trying to take their Indian customers' granted...Treating them as Europeans' used to treat us 65 years back... Renault TRYING TO CHEAT INDIAN CUSTOMERS’!!! SHAME!!! running pillar to post ___but no solution from RENAULT...
