State Bank Of India [SBI] — Unauthorized transaction made from my account by OTHPG 266316 Hostinger Mumbai from my debit card

Address:

Cooch Behar, West Bengal

On September 13, 2023, My SBI account got debited by debit card OTHPG 266316 Hostinger Mumbai for Rs.3242.64/-. The unauthorized transaction didn't even have a transaction message sent to me by the SBI bank.
I made a complaint to my SBI bank branch, but they didn't provide me any satisfactory reason for the issue.
kindly see to this matter and help me get the refund for the unauthorized transaction made from my SBI debit card.
