When viewing your bank statement, it is important to review each transaction and ensure that you clearly understand what has been deducted from your account. If you notice a deduction that seems unknown or erroneous to you, it is imperative to contact your bank immediately to clarify this transaction. It's possible that this deduction is related to a direct debit, purchase, or service fee, but it's important to understand exactly what's going on with your money.

Indeed, it is essential to keep a close eye on your finances and regularly monitor your bank statements to avoid any fraud or error. If you don't understand a transaction, it's best to report it to your bank immediately to avoid future confusion or complications.

Also, it is important to note that deductions can sometimes be the result of bank or merchant error. In this case, it is important to report the error as soon as possible to avoid financial harm.

In short, it is crucial to remain vigilant and regularly monitor your bank statements to avoid any confusion or error. If you notice an unknown or erroneous deduction, do not hesitate to contact your bank immediately to clarify the situation and protect your finances.
