Hyundai Motor India — False commitment by dealer in Ranchi (Republic Hyundai)

I have booked Creta SX IVT 1.5 MPI on 08th October 2020 from Republic Hyundai Ranchi. While at the time of Booking it has been advised to me that Vehicle will be delivered by October End. Subsequent to this they have committed that Vehicle will be delivered by Nov2020. Now again this date has been crossed and now they are telling most probably vehicle shall be delivered by Dec-20 or Jan-21. My only submission that whether this is an acceptable proposition in Hyundai to make a false commitment and to force to customer to think that they have made blunder in booking Hyundai Vehicle. Request you to intervene and see if deliver can be delivered in next 15 days.
