Mahindra And Mahindra — Dealership inappropriate behavior

I have booked ax7 L AT D on 18th OCT 21 and the amount paid on the same date but the OFT number was generated on 26th OCT 21 .and the dealer says that he could do nothing for that. lot of mails return to MM but they are saying that it could do nothing for the mistake done by dealership.
so is this what MM gives a reply to the customer?
next thing if by any chance the car breakdown then also will you say that we are not responsible for plant mistake?
