Vishal Mega Mart — item removed during billing but cost is added in bill

Address:

D- 386, surya nagar, Alwar, Rajasthan, 301001

During the billing time a dispute rise in the price of price. For checking they took the product for some inspection but they were taking too much time so I said to remove the product and do the billing. The price of product was 250 but the counter by mistakenly discounted 25 RS only not 250.
But now I have paid 225 RS and do not have the perfume too.
