Hyundai Motor India — Extra amount

Address:

Siwan, Bihar, 841226

Hi, my name is vivek. I bought grand i10 sports from musafir hyundai siwan. At the time of booking they quote price 5, 70, 000 and i got the quotation. When i went to make the full pay and bring the car. They make the total bill of more than 6 lakhs saying that car price has been increased. And several times i tried to contact with mr. Sandeep ( i think he is owner of the agency), but his phone is getting switched off. I am really fed up with it, i have already paid 15, 000 extra, not i want my money back other wise i am going to file a case in consumer court. At the time of booking the car, i had given 15, 000 and lastly i gave 1 lakh by rtgs and rest 4, 70, 000 by sbi car loan.
So please look into matter.
