No English for African bank

How is it possible for an organization the size of African Bank can Employ consultants who cannot speak English properly?

I have been a credit card customer of African Bank for many years now, during October 2020 I moved my current bank account, I e-mailed African Bank and advised them to change my bank details for debit order purposes. The debit order went of my new bank account once....and never again (I confirm there is/was enough money in this new bank account) Today I received a call from the most arrogant individual ever, and to top it all he cannot speak English properly. I asked him why the debit order is not going off. Unfortunately he cannot answer as the language barrier is to big.

So, can African bank please send me the total outstanding amount on my credit card, as well as the details of whereto a can pay (EFT) this money. I would like to settle this card and never deal with these bunch again.

Many thanks Werner Roets
