Pothys — Debited amount twice for one bill

Address:

Saidapet

I bought goods from pothys on 27 jan 2023. I paid the bill amount with my debit card. The cash person made me enter card details in card machine and after few moments said that card didn’t go through and so inserts my card in another machine. He said my card went through in second card reader and bill paid.
After I got home and checked my bank details I realised that amount has been deducted twice for same bill. I called up store again and they said amount will be credited shortly. But till now I didn’t receive it.
Kindly look into this issue and credit my money back into my account at the earliest.
Thanks
