Angry Customer!!!

I am so disappointed in Fnb actually not just disappointed but upset! I have reached out to the chat system on the FNB app yesterday because I was having issues on my app where I was unable to generate a proof of payment. They passed me from one agent to another for 2 hours until one of the Aspire service suite consultants by the name of Tshenolo confirmed she would send me my Transactional statement and promised it would be free under the circumstances. This morning I wake up to a negative balance because of an interim statement fee on my account. I reach out to the chat system and not even 1 consultant expressed any empathy instead I was told to lodge a complaint. 1 of the consultants literally spent 5 minutes reading my chat then just transfered me to another agent. The incompetency and terrible customer service is disgusting and I need someone who will go through my chat history for today and yesterday and investigate this and provide a resolution!!! I am sick and tired of FNB, if you cannot hire the right people and provide them with the right training so they no what they are doing rather close the Chat line because it's such a nightmare!!! Very disappointing for such a big bank!!! I am so annoyed and upset!!! I want the statement fee charged on my account removed as it was not supposed to be charged!!!
