Rude banker on the Fnb chat app

I was trying to find out about transactions that went off on my account and decided to go to the chat on my Fnb app and was put through to a person called Tashony who was very rude to me and decided to cut our chat while I was telling her about what happened. I then tried to connect to a different banker and I got the same person who again was rude to me and did not want to give me information about transactions that going off on my account.
