I booked Nexon XZA+S Flame Red Petrol variant on 28th jan 2021 from key motors, bangalore. It's been 7 months but no sign of vehicle allotment, From last 4 month i am getting 2 excepted date range each month. Dealer is telling they have nothing to do tata is providing them vehicle and if i connect with tata customer care they simply forward the request to dealer.
