Needs training in customer service

My name is Camille Smeers I did an application for an American Swiss account online and I got notification that if qualify so I should get my card at the Alberton Mall with my ID and proof of address. I went to the branch and waited very long for service even felt uncomfortable. I walked to a lady and she was very rude to me like I was disturbing her if, I told her my story and she said she wants proof of me qualifying. She made me feel that just by looking at me she knows I don't qualify basically she was judging me. I asked her if she can show me proof of what I should bring her she asked me if know about a customer's privacy and she can't show me other customers things, I told her that the website didn't tell me to bring proof that I qualify but she said she can't help without proof and carried on with what she was doing while I was standing there am very unhappy with the service if received and would like an apology, I asked her for name and surname and she asked me why I told her I am going to put through a complaint, she gave me the name Goitsie and she said she will never give me her surname. I was at the branch on the 25/04/2015.
