Very poor customer service

After standing on a queue for 45 minutes, the teller by the name of Buyi told me that the coins I'm depositing are not sorted correctly. I tried to apologise and explain to her that I was just sent to come and make a deposit, and that I was not aware the coins were not sorted correctly. But to my surprise, she just yell at me, saying she doesn't care if I was sent or not, and she's got a right to turn me away. I politely ask her to stop yelling at me and that I'm not in the mood to argue with her, because I've already apologised. But she kept on saying I must tell the person who sent me that next time she will not assist me. <br> Anyway there is no next time for me because I'll never set my foot at FNB Jabulani Mall ever again. I'm so disappointed because I've never had such a bad customer experiment at FNB.<br>
