Pick and Pay ********* customer service

A few months ago I joined the Coffee Club and The Wine Club via Pick and Pay and their Smart Shopper card. I used it a few times at the Durbanville store. I discovered however that if I enter for competitions and certain draws and benefits, I never get confirmation that I have been entered. That was suspicious. While I am making an effort to complete and submit everything, they may never receive it, or capture my entry. On following up with PnP customer service, I received a very strange email reply. I provided my contact number, email address, as well as my Smart Shopper card details, but the customer service liaison, Shakeerah Adams, requested more personal details before she can assist me. Besides all the above info, she also wanted my ID nr, as well as my physical address! I was very surprised and rep**** that I refuse to give her such info that has nothing to do with my enquiry. POPI Act applies. She was adamant that I have to provide all that personal details. All I wanted to know is if the Coffee Club ever receives my entries; surely my Smart Shopper card can be linked to that? They are quick to send you marketing messages - why not as effective in confirming your entry? Unless they indeed do not process these entries; and meanwhile we keep entering foolishly. Because she was "unable" to assist me unless I provide even my physical address, I gave up and requested to be removed from all their marketing notifications. But then the situation became even more absurd. In order to remove me from marketing notifications, she required not only my mobile nr, my email address and my Smart Shopper card details, but ALSO my ID nr and my physical address! I refused; and needless to say, I cannot get rid of their marketing messages till today. If Shakeerah Adams is just applying the Pick and Pay policies, then I rather shop elsewhere and don't use my Smart Shopper card. There are enough alternative shops in my neighbourhood. There is no benefit in supporting the Pick and Pay Coffee Club, or Wine Club; there are good prices elsewhere too.
