**** Attitude & no call back

I got a statement via email for an acct that I dnt have. I called the call centre and spoke to Nomtandaza. I gave her the card number and she did a sec check with me and I passed all her sec questions. When I told her that acct wasn't and what address she had, she told me the same one I gav her. I told her its ******* as Im in JHB and the add on the statement is DBN. I then asked her to read back the id number that she has on system that she confirmed with me. She got stroppy so I asked to speak to her manager. She kept me on hold for over 5mins...I cut the call and redialled and I got back to her. This time she simply refused to speak to me or help me, she was just silent, so I swore her and cut the call. I called their switchboard and after speaking to their ***** dept was put thru to cust serv again. Ziyanda advised me that she will escalate the matter to her team leader Shaun who will call me back...4hours later and Im still waiting for his call!!
