Inadequate security check & cards issued without proper authentication

My query was initially sent through my private banker. I currently possess bank cards that are inaccurately reflected on the banking app, which displays cards that I do not own. Today, I received a call from a consultant named Landi. During our conversation, I informed her that I needed to retrieve the cards from my handbag, which was in my car parked in the office ba*****t, before we could proceed. I requested that she call me back at 2 PM. Despite this, she insisted on conducting the security check for the 2 PM call, which raised concerns for me. Given the current climate of *****, I am apprehensive about the security measures in place. You called me at 10:35 AM and planned to call again at 2 PM. How can I be assured that I am speaking to a legitimate representative of the bank? The security questions asked included my ID number, cellphone number, and residential address. The request for my residential address, in particular, raised red flags. The security checks conducted by Standard Bank are concerning. How can customers be certain that they are speaking to bank staff, especially with the prevalence of *****? This situation has led me to question the value of the prestige banking fees I am paying, as the service provided does not meet the expected standards. Keeping this in mind, how do we resolve my issue of the cards in my possession.
