Worst service, ****** teller

I went to Laudium branch to withdraw 15000 and the bulk teller who had no name badge on literally refused to give me my money. She asked where the funds came from I told her, she says she had to ask because its procedure then after she had been googling my account I asked what is the problem. She said she has to check, what specifically she could not tell me. I only went into the branch because of the amount and because I am black she was just suspicious of me. I told her I'm on lunch and she is wasting my time. I was told before that if larger funds come into my account they will be investigated whey come from if I try to access them before 48hrs.well the money has been there since Friday and I have already used the account several times since then. But just going into Standard bank Laudium I'm treated like a ********* for a mere 15000. I have withdrawn 31 000 at the same branch with no hassle.according to me that woman is ****** and her attitude towards Africans should be put in check. Oh and I left the bank without my money and she said did you take your card. Rude.
