Bad Service!!!

I was assisted by the consultant with the app on my phone and it looked like it was working. The second I stepped out of the bank the app didn't work it said its suspended. Frustrated I went back in the bank to ask the consultant what could be causing this. When I got to the door I was met by a foul gentleman whom I told the story of how I had just been here and I just want to show the consultant that the app is not working still. I pleaded with him to please allow me to go and ask after the consultant is finished assisting the current customer. The gentleman at the door was now irritated with me and told me I just have to stand in the queue all over again and that that's how life works there is nothing he can do. He said this while attending the next person, leaving me just standing there with noo assistance. Luckily the consultant that had assisted me saw I was back and was stunned that I was not allowed to go ask what I wanted to ask from her. She called me over, which I was not allowed to do by sbongile, who refused to tell me his name also as he was not wearing a name tag. I raised this at the brnch with a lady who said she is the asistant manager. She has not goten back to me
