Very unhappy FNB customer

I reported an authorised payment that went off my account on 11 Feb 2025. I received a email from FNB to send proof of everything which i did. Since then I have to heard a word regarding the matter. I went on the FNB chat all they do is transfer me to someone else. Today 27 days later still no response i am really very unhappy with how they deal with disputes.... Capitec handles a dispute so smoothly WHATS WRONG WITH FNB!!!!
