D-Mart / Avenue Supermarts — wrong price charged

Address:

Mumbai City, Maharashtra, 91

On[protected], i visited dmart at bhayander west and bought some house hold goods and a t shirt having mrp rs 185/- and dmart price 149/- vide bill no.[protected] dated 19/05/2019 for rs 2614/- and paid the full amount via my card. Surprised on checking the bill at home that the said t shirt is billed rs 185/- in place of 149/-. I call on customer care number, they reply and asked me to come at dmart for checking. It is not possible to go again to claim rs 36/- difference amount.
It may be happened with number of customers for small amounts and most of them will not go to claim considering the cost of claim.
If it is happened inadvertently, it should be fair business practices to refund the excess charge amount to the customer at dmart cost.
Awaiting reply.
