Royal Enfield — Bike not delivered yet

I booked Meteor Supernova on 8th of August and the tentative date to deliver the bike was 6th November. It’s almost 2 months now from the date of delivery the customer care people says that the bike is in manufacturing and when asked they do not have any future date till when the bike will be delivered. Even the car waiting is less than this bike. I don’t understand on what grounds are you guys booking these bikes and saying that the same will be delivered within 3 to 4 Months. Please note that I booked a Royal Enfield not a Rolls Royce.
