Still waiting for a call from African Bank

On Monday 14 December, around 8am, I called African Bank for 2 reasons. One was to find out when the R3000 they had debited from my cheque account will reflect as available funds on my credit card, and secondly, I needed them to confirm the correct USSD code to be used when making enquiries on my account since the one that I was using does not work. I was transferred to a Nhlanhla who is a supervisor, who promised to call me back in 5 minutes. It's been over 4 hours and I am still waiting for his call. I am so disappointed at the level of disservice from African Bank, and the fact that they have such people manning the call-centres is just frustrating!
