Incorrect fees charged and cannot be reverted

What a terrible bank. I joined the bank on the 27 of August 2019, choose the pay per transact option on the platinum account. On the 27 September they charge me banking fees of R278, for what? Nobody knows. I call them(08/10/2019) to complain, they acknowledge the mistake in being incorrectly billed, I receive an email confirming this. And they continue to say "The issue has been raised and a fix will be done on your account in the 7-10 working days".

I call them again today 17/10/2019, and they say they will escalate the issue and revert back to me, A guy named Hloni calls me this afternoon and tells me he got the feedback and apparently I am not the only one affect by this issue and now they're working on a bulk fix and my account should be fixed in the next couple of weeks. COUPLE OF WEEK? HOW? How does something like this happen and you guys cant simple refund people's accounts individually? And how does this affect a lot of people? How do you bill people incorrectly? We you hoping they won't see and in the process you'll make money? That's it, I just want my money back and then I am closing the damn account again. I am never recommending anyone to use your bank. YOU'RE THE WORST BANK RIGHT NOW. *******!!!!
