How can we help you get furious?

Received horrible service at FNB Brandwag in Bloemfontein. Came in and the lady asked me to write down my name (she did not say why though) and told me to go sit. I sat down and had a look while all the people who had a seat before me where helped. When my turn arrived, I went to the consultant's desk and requested my house's deeds. Right in the middle of the process another lady came up to me and told me that I should leave cause I jumped the queue. I asked her what queue and she said the one where my name was written on, I was not aware of any queue except of the people who had a seat before me. By this time the lady who initially told me to put down my name was now in something that seems like a stand up comedy show as she was having a ball telling jokes. I then decided that I will leave as FNB clearly does not want me in their branch. FNB, if you don't want me at your branches, please put an ad in the paper that reads: \How can we help you get insanely angry at us?"Absolutely furious"
