Awful service with credit cards

Absolutely shocked with the service I have received with regards to my Credit Card, firstly the number on the back of the card does not take you to the credit card department, and everyone you speak to is so arrogant and useless that they can’t transfer you to the right department, get sent from pillar to post, FNB debited my card early instead of the end of the month as agreed, I eventually get told I was sent a message on the 13th in the app, and it my responsibility to stop it, I received no message, the only message I received was a sms on the 12th saying it will be taken off on the 31st, I have screen shots to prove this, when I told the person I was speaking to that I received no message she refused to listen and spoke to me like I’m stupid, when asking to speak to a manager I was told managers are not allowed to take calls, only after I insisted was I transferred but no manager ever answered. My trust with my own bank is now gone, how can I trust FNB to keep my money secure if they take it themselves without my permission.
