BAD CUSTOMER CARE

This is my 2nd bad encounter with this mean lady. When I opened my account at FNB in 2012, they were aware that I'm a foreign national with a passport as form of Identification. Last year, I wanted to withdraw some cash inside the branch for it was a huge amount. I went to FNB Broadacres and this Thembi lady refused to assist me and said because I am a foreigner, I must wait for 24hrs before any withdrawal so that the bank can investigate where I got the cash from. My boss was there and she had to intervene on my behalf because she had made that deposit for me and it was from an FNB account so it had already cleared. The same incident happened last week, I was so humiliated by the same Lady Thembi again. I'm waiting for my perm res permit. I produced my receipt and asked her to verify with home affairs. She started humiliating me inside the banking hall shouting that if I don't sign a certain form she is going to block my account. I have never been humiliated like that in my account. I told her that I have been assisted at other branches and she said their rules are different. I am so disappointed.
