Disputed Transaction and Poor Service

I'm extremely disappointed with the service I received from FNB regarding a disputed transaction.

On 1 Feb 2025, an unauthorized transaction was initiated from my account. I immediately contacted FNB, but was told I couldn't dispute it because it was pending. After the transaction processed, I tried to dispute it on the app, but the option wasn't available. A consultant advised me to email ***.

I emailed on 6 Feb 2025 and received an automated response promising a resolution within 5 days. It's now been over 5 days, and I've received no feedback or resolution. The transaction has also disappeared from my app history
