Mahindra First Choice [MFCWL] — refund booking amount

Address:	560038

Hi,
I had booked hyundai i10 grand sports 2015 model from mahindra first choice indira nagar bangalore dealer superior motors by paying 20000. But due to some financial problems i had to delay the purchase of the vehicle.in the meantime they sold of the vehicle without notifying me and even at higher price and when i came to know about this, they said that they would find me a car that meets my expectations. But they were unable to find another car and when i asked for the refund they denied to pay it. I understand there is some operational cost incurred buy them for holding back the car for me but that in no way can amount up to 20000 rupees, they are fooling there customers.
It would be very helpful to get a resolution on this.
Thanks,
Sayantan
