State Bank Of India [SBI] — Issue regarding SWAP transaction

On 23rd feb 2022, I have paid my fee through debit card and the amount was 26, 000.The transaction was successful and I got the receipt back after the transaction and even I got a message that 26, 000 was debited from my account to the merchant. But on 1st march 2022, at 10:40 pm, I received a message that 26, 000 was debited and my account balance is displayed after getting debited. Though I haven't made any transaction with debit card after 23 feb, my amount got debited. I want a refund on this amount or will I get the amount back? Is it possible? Please tell. Actually I am in need of money because of my father's illness. Please help regarding this issue.My phone no is [protected].
