Address:

400068

I have purchased some commodities worth rs.534 from dmart dahisar west mumbai on 19.02.2020 using andhra bank debit card. The transaction was declined twice and so i did payment using cash. But the amount was deducted from my account for both the failed transactions and i have not received a refund for the same inspite of making a complaint at the dmart customer care section dahisar with the bill.
