Prevent credit on my profile

I went to Capitec riverside mall branch on 04 March 2016, where i was served by Charmaine, I wanted to apply for credit. She had a very bad attitude and she was asking me questions I've neer been asked by Capitec before( how many kids I have, etc) . She took over an hour checking my documents, only to tell me that I'm not being approved for any amount. I knew she didn't want to serve me so went to ilanga mall branch and to my surprise, Charmaine has put a \ no credit\" restriction on my account, so nobody can help me now. What made me more angry is that she told me from the beginning that she doesn't think I will get the money. Capitec bank has been providing me with credit ever since I started working, but the service I've experienced has left me speechless. How do you block someone's account without even informing them? Even her colleagues at ilanga mall were really baffled. Bad service to the core."
