Maruti Suzuki India — Car not received

Address:

Gurgaon, Haryana, 122001

Dear sir,
I m Varun chawla residing in Gurgaon, as I already booked baleno delta 1.2 at Nexa Pasco Automobiles in sikanderpur gurgaon before 3 months . During booking as I already mentioned that there is my sister marriage in October. But before few days they called me and said wll give u the car at the end of sep16 but now when i called for purchase they refused to give and say wll give u in November.
Sir pls tell me one thing, can I change my sister marriage date for this .. If I wll not get the car it's very bad thing for me. Which is also not good image for u as u can understand what I want to say.
Pls sir I request u to do best possible for me and take on priority.
Though this I can gift baleno car to my sister on marriage.
Thanx & Regards
Varun chawla
