Indus Motors — Delivery delay

I booked my wagonR on 9th jan 2022.The sales executive promised me to handover the car after 15 days. After that i paid 30k and within 2 weeks i paid the whole amount rs 6.47lakhs. Then i called him often to fasten up the delivery. He always ensure different dates for delivery but he did nothing for that and i also contacted the manager of kumbazha. As far as there is no response from the manager also. The sale executive promised me that the delivery date could be 10/02/2022.Today the friend of mine from RTO contacted me and asking for the invoice. I frequently contacted the exective for the invoice.I waited there for 1 hour then i get a invoice.Then the RTO officer told me that the car delivery may be in next week
My daughter marriage is on feb 14. I booked this for gifting my daughter.Your irresponsible behavior disappointed me as well.I regret for selecting you for my daughter big day.I never gonna buy any car from indus motors.
