unsafety of bank account

Dear Nedbank Customer Service,

I'm writing to express my concern and disappointment regarding the safety and security of my Nedbank credit account. Yesterday afternoon, I received a call from a registered Nedbank number regarding a suspected transaction of R8,700 from my credit card account. I informed the representative that I didn't authorize the transaction.

She requested that I accept a po up verification text, which I did. However, after realizing something was amiss, I immediately called the *** Nedbank number and spoke to a representative. They confirmed that the money had been ****** via a card transfer, despite not using my card for two weeks.

I'm shocked that I didn't receive any notification requests or transaction confirmations, unlike usual. This raises serious concerns about potential internal breaches. I urge Nedbank to conduct a thorough investigation and resolve this matter urgently.

Specifically, I'd like to know:

1. Why didn't I receive notifications for this transaction? 2. How could this unauthorized transaction occur without my knowledge?

I request a speedy resolution, return of my ****** funds, and answers regarding the investigation.
