bad terrible worst service!!

So today I had mistakenly blocked my card pin I then went to the branch (Westgate Mall,Roodepoort where one of their consultants sold me a product without my consent but that's in the past and I have let it go) but today when I went to the branch and asked to see a particular consultant to assist me quickly since I also work for a neighboring bank the lady at the door refused,I said ok and walked away,then I went back for the second time hoping she'd let me in she then gave me a ticket and at that point I didn't mind waiting because I was frustrated,she then had the guts to go to her manager (Nathi) and told him that I was being rude,did the manager not go to my manager and report me in my absence!! Now what I want to understand is,does FNB investigate all their clients and report them at their workplace? Not only did they put my job on the line but infuriated me on top giving me bad service whereas I was being polite to them ,I know what its like to deal with rude clients now why would I want to do that to somebody else. I literally greeted that lady with respect compared to the client that was in front of me who just walked past her like she was invisible. I am really disappointed at the manager and the treatment i got from the lady that was standing at the door. She was wearing a white tshirt ,glasses and had cornrows.
