Dear sir/ ma'am,
I placed an order for groceries from big bazaar site on 28/04/21 from and paid online.My prepaid amount of Rs.2546.75 for order no.[protected] was cancelled from their end. When I tried to track the order on 29/04/21, it was showing that order has been cancelled and the amount from my bank account was also deducted. I tried to call them on customer care numbers, sent mail and many messages on their site regarding the same but didn't get any response from their side.
