***** by Capitec Bank

Capitec they are ***** stars, they took money from my account claiming that it is a duplicate payment, whereby what ever they are saying it cannot be proven it doesn't appear anywhere in the statement. Currently I can't even pay school fees for the month for the kid's, and other things. So Capitec users please check your accounts, the bank itself doing *****. I took this matter to them and the only thing they say is that they are investigating. How can a bank investigate itself?
