I had swiped my debit card 5044xxxxxxxx3058 at reliance fresh store at poonamallee chennai for rs 2390.31 on[protected]. The amount rs 2390.31 was debited from my account but reliance store person told me it was a failed transaction. Therefore once again i swiped for the same amount which was successful. Store official has shown the failed transaction voucher and stated the amount shall be reversed/refund to my account shortly.in spite of many days are over the failed amount is not yet reversed/refunded/remitted into my account. When i enquired with bank i am told that the transaction is successful and amount is credited into pos merchant reliance fresh. But reliance fresh has not refunded to my sb account.
