African Bank put my MyWorld account on hold (freeze) without notice or reason. Not even responding, even after 72 hours and 2 tickets logged

About a week ago I've noticed that my MyWorld account no longer has a "pay" option (Internet Banking). I could make no bill payments causing huge embarrassment and affecting my credit score. I've logged the problem with African Bank on Sunday, 17 Jan (***) with a promise "We will provide feedback within 72 hours". Needless to say, the 72 hours lapsed and I had ABSOLUTELY NO feedback from African Bank. This morning I also phoned African Bank for feedback, using the same reference nr and was told that it's been escalated and that African Bank would "phone me within the next hour". It's now more than 12 hours later and I still haven't received any feedback. In the meantime, I've discovered that African Bank put my MyWorld account on hold (freeze) and did not even had the decency to notify me or give me a call. It's really a shame because my wife and I invested more that R6m in African Bank and are being treated like this. Once the problem is resolved, I'll close all my African Bank accounts and will invest my money with a reputable financial institution. Think twice before investing your money with African Bank!
