[Resolved]  Maruti Swift Dzire — waiting for last 2 months after paying full amount

I was informed by Sales representative of Bhandari Automobile that we have Swift Dezire avilable and we can deliver it in 1 week. I payed the balance amount and applied for 4 Lacs loan. Load took 1 week after our discussion. Once loan was passed I asked them to handover the car they told since loan took time we have delivered the car to some other customer.
Date of payment (1.54 lacs) - 22nd May (Approx.)
Loan Disbursement(4 Lacs) - 27th May (Approx.)
Dealer - Bhandari Automobiles in Howrah
Still I am waiting for the vehicle, I asked Mr Jayanta Bose (Bhandari) and he told there was no vehicle in the month of May, how come somebody will promise it for you. Since then I am getting only dates and no vehicle till date. Mr. Bhandari has given a number of Maruti representative Ms Priyanka Ghose and she told it may take till August end.

Please advise what to do?
Thanks
