Rude and abrupt

So on friday 2nd of Feb at around 4:15pm I called into Std Bank customer care to get help in transferring money from one account to the next. The agent to who answered was firsy very rude. When she asked the reason for my call i explained that i used to transfer money from one account to the next on my banking app for the last 3 months but now for some reason i cant?. She proceeded to tell me that isnt possible, i wont be able to transfer? I told her to 1st take my details so she can see on my profile that in fact i have been doing so for the last few months. She then very rudely confirmed my security check and then insisted that I didnt know what i was talking about to the point that i got so up set, I hung up on her. Now i dont know if ir was because it was maybe time to go home that she didnt want to help, but i am utterly disgusted by the service. I have been with Standard bank for over 10 years and this i find totally unacceptable. I haved worked in a call centre and I know that is not how u treat a client. She didnt even bother checking my profile to see that i was able to do the transfer before. I am very unhappy something so simple could have been sorted out.
