TVS — tvs charging 2% extra on credit card payment from customer

Address:

Bangalore, Karnataka, 560017

I am purchasing a bike from tvs in bengaluru. As per the guidelines from rbi it is unfair to charge 2% extra from customer if they are paying through credit card. But tvs is not willing to sell vehicle without this 2% extra charge. They told me not to buy the vehicle from them and also they will not include the details of this transaction in the original bill.
