worst customer service

I'm disgusted by poor the service I received. I was there to deposit,but due to the construction that was taking place the servers were off line, which I was told after I had sat there for over fifteen minutes. The consultant who told me this in a rude manner then asked me why I was sitting and not standing,because people who deposit stand,I then asked her if I was required to stand while the servers were off line. I then asked to speak to the manager and she told me to call the manager myself and she wasn't going to help me anymore I would help myself and indeed she didn't call the manager or attend me anymore and as the other consultants came to speak to me which was point less,because they spoke when I spoke and neither of them even apologised for the inconvenience, while the consultant who refused to call the manager laughed to my face a few steps away. As I still requested to speak to the manager I was told he or she was not present.
