NO FEEDBACK OR CUSTOMER SERVICE

The day after I got a card from African Bank, R2000,00 was taken out of my account by ****mers in Malaysia and I have never even used my card, up to that point. How did they get the number, if the card was never used? This happened on 1 February 2023. Since then, I have, literally, every Monday, copied all of the previous emails that I sent to African Bank for them to try and get my money back, to them, but I never get any resolution. I get a message stating that the bank tried to contact me, with no answer. I never get any calls or emails from them. When you call customer service or go to the bank, still no resolution. I don't know where to turn to anymore, maybe the Banking Ombudsman? Surely, as a client, a person is entitled to customer service, which seems to be non existent?
