Bad Service

On the 19th July 2023 I used the FNB secure chat and spoke to Sinethemba Mlangeni. I'm so disappointed, the agent was unprofessional as she ended the chat after telling her that I don't understand her explanation. The only thing I requested was to change my Debit Order date and confirm when will the next Debit Order go off. She lacks knowledge because I asked about pro rata and she said there's no pro rata. She refused to give me her manager's name and surname. I still want her manager to call me back as I feel she needs to be disciplined and trained. I'm still clear about the answers she gave me and I don't deserve such poor service especially from FNB as I've been a loyal customer for more than 15 years.
