Near impossible to cancel, footed with the bill while abroad

I had three bank accounts in South Africa. My experience with this one has by far been the worst.

I moved to Germany in October last year. I kept my Discovery Bank account active initially for emergencies. However, I tried to close it afterwards and the only way to do so is telephonically, and you can't email them to follow up.

1. There is no e-mail address to contact Discovery Bank on the website. 2. I was assured by two assistants on the phone that my account would be cancelled, which it was not. I don't understand how this is my fault? 3. I am now being told that I have to pay R2700+ in bank charges for an account that I tried to cancel, that they made near impossible to do. 4. I receive an e-mail at whichever time they feel like responding (could be a week), then get 1-3 days window to pay a specified amount.
