Unexplained 1200 TL Deduction from Yapi Kredi Account

Yapi Kredi Bank recently withdrew 1200 TL from my account without prior notice or explanation. This unauthorized deduction has perplexed me and made me concerned about the safety of my funds. I am completely unaware of the nature of this transaction or the person or entity responsible for it. My immediate and primary concern is to recoup the 1200 TL deducted. I believe I am entitled to an explanation of why and under what circumstances this deduction was made. Furthermore, I'd like to know how this unauthorized transaction was permitted to occur in the first place. It is critical for me to protect my financial assets and make certain that my account is not compromised in any way. In summary, I'm looking for help recovering the 1200 TL, obtaining a thorough explanation for the deduction, investigating the origins of this account, and eventually closing my Yap Kredi account to prevent future unauthorized transactions.
