Insulted By Call Center agent Vuyokazi Kimbi

I received a call yesterday @17:38 from the number 0218143700, ARA's Legal Department. She introduced herself as Vuyokazi and told me the conversation was being recorded. She asked to speak to \Malibongwe"and i told her i'm not the guy she's looking for and that she might have called the wrong number. The lady started to be rude claiming i admitted to being this \""Malibongwe\"" guy earlier. She told me to confirm my identity numbers and i told her i was not gonna do that to a person i dont even know and have a business or purchase agreement with. Seeing that this vuyokazi lady is boiling and fuming at me for not giving her answers i asked her plz give me her full names and the company she's working for but she refused saying that was \""NOT IMPORTANT' for me to know she just wants me to confirm my identity"
