No altenative verification process for ***** Victims

I've been struggling to log into the pick n pay app to keep track of my smart shopper rewards and deals but the app was not recognizing my username so I called the contact centre today (22 Feb 2019) at 14:31 to get that sorted. The first thing the consultant asks for is my IF number I advise her that I'm not comfortable sharing that over the phone since I was victim of ID ***** a couple of years ago and one for the precautionary measures provided by the South African ***** Prevention Service is not give my ID number over the phone so most services providers even the banks understand this and are willing to take my birth date or they recite my ID number back to me for verification, but my point is that they have a process in place for people like me who have been victims of previous ID ***** and are just trying to protect themselves. But not Pick 'n Pay. No this consult insist that I must give her my ID number because it's the 'most important requirement' for her to help me and there are no other options. I then request to speak to a manager so that I can explain my situation, at this point I'm wondering if it's actually worth it for a rewards card to be going through all this as if I'm applying for a loan, but I forget ahead anyway. The consultant then tells me that her manager will tell me the same thing anyway and I should somehow ended reassured that their calls are recorded (not sure what that has to do with my current query), she finally agrees to put me through to her manager but then I'm kept on hold for so long that I decide to give up and log this compliant instead. And I have worked in contact centre environments before and know all the tricks in the book, I was purposefully placed on hold so long without her ever coming back to check in until I would hang up the call then it doesn't register as a dropped call from her end but a rather a dropped call my end. It's been a disappointing experience and honestly the only answer I'm actually looking for in this instance is why Pick n Pay for their rewards card does have a process in place for victims like me. So we shouldn't bother trying to participate in this rewards scheme of all things. Wonderfully service Pick 'n Pay, I was a loyal customer for as long as I can remember shopping but I think you've just lost me to Checkers and Woolies instead now.
