Toyota — False promise for car delivery

Have booked toyota hyryder base model with sharayu toyota Aurangabad on 4 Nov 2022 with commitment of car delivery in the month of Dec 2022. After confirmation of dealer I have booked the car till now I didn't get any clear answer for that. On what basis dealer are accepting bookings and now telling answers that company not telling anything about deliveries, quality check etc. My 2 month waiting period is already over and 4 th month almost to end. There is no answer from anyone till now. All other upper models are avaliable but not this base model.
What policy company is using with customer to force them to modify the booking with upper model? If company dont want to sell its base models then why they have introduced it ? It is very unethical... This is worst experience with Toyota. Please let me know the status and deliver car as early as possible
