Serious Concern: Repeated Unauthorised Charges on My Account

I am writing to formally lodge a complaint regarding repeated unauthorized transactions on my account and the continued compromise of my card details. On 5 May 2026 at approximately 03:25, an unauthorized transaction from Steam was processed on my account while I was asleep. This is not the first occurrence, this is now the third time that *****ulent transactions have occurred on my account. Following this incident, my card was blocked due to suspected *****. However, I am extremely concerned that:

My card details have clearly been compromised This is a recurring issue, not an isolated incident I am once again required to contact the bank manually to resolve a serious security breach

While I understand the need for identity verification, I find it unacceptable that repeated ***** has occurred without stronger preventative measures being put in place after previous incidents. I am formally requesting the following:

Immediate reversal / chargeback of the unauthorised Steam transaction from 5 May 2026 Issuance of a completely new card, including:

New card number New expiry date New CVV

A full ***** investigation into how my card details were compromised Enhanced security controls on my account to prevent further incidents,

A written response explaining why repeated *****ulent activity was able to occur despite previous blocks and interventions

The ongoing nature of this issue has caused significant inconvenience, stress, and concern about the security of my banking details. I expect this matter to be treated with urgency and escalated appropriately. Please confirm receipt of this complaint and advise on timelines for resolution, investigation outcomes, and the re‑issuance of my new card. I trust the bank will take the necessary steps to restore my confidence in the security of my account.
