Capitec failed me

It's now the 4th month since my bank cards were blocked. Everytime I do a follow up I'm being told they are still investigating. I borrowed someone money sometime in June, transferred from my credit card to that person's FNB account, the money was transferred back after 3days. That's when I received a notification that my cards have been stopped. I went to the bank I was told to bring an affidavit explaining the problem and attach my ID copy together with an affidavit from the person whom I sent the money to. I submitted everything and the response was "they will reverse the money that was received from the FNB account inorder for them to open my cards" I've been waiting ever since.
