State Bank Of India [SBI] — deducted amount even when transaction failed

Recently i used my debit card for some purchase on 22.01.19. For an amount of 1333.00. The transaction was shown as cancelled. But when i checked my account the amount has been debited. I had repay the amount again on 25.01.19 on request from the shop owner. Usually such debit gets reversed but now even after 10 days the amount has not been credited back to me.
