Reliance Fresh — Money not refunded back

I made two payments on 6 April 2022, of rs 155 and 215 rs. 215 rs paid for the items I got. I was asked money of 155 rs wil be refunded.
Even after a month I didn't got money.
I enquired both customer care of bank and reliance fresh.
Bank says transaction done we can't do anything, reliance customer care says we got 1 time payment ask bank for money revert back.
No body trying to co-operate. Kindly see the matter please.
