RCS - Pick 'n Pay Store Card - CLUELESS

Received sms Friday to collect my card in-store, got to store and was told they just need to link it to my smart shopper card. Phoned them and after 3 phone calls I got it done and had my pin no. Went to store and did small purchase to test and it worked. Loaded my trolley with what I needed and it declined. Store tried phone customer service 4 times with no luck. Went home and phoned them. My card was blocked due to possible *****. Went back to work, emailed a copy of my ID with 3 signatures. Phoned them and answered the 20 questions and they unblocked the card. Went to pick 'n pay 'n pay liquor store on Saturday - DECLINED again. Phoned again 4 times before being assisted - Card was still partially blocked. Answered the 20 questions again and they unblocked. Went to pick 'n pay grocery store - DECLINED. Phoned 5 times before being assisted and was told that I need to phone them from the store when I make purchases so that I can be verified by ***** department. So I have to get my stuff every time go to the till, wait for it to decline and then phone them (if I have enough airtime, because it takes approx 15 minutes per call - IF THEY ANSWER). Then I have to answer their 20 questions and if this is not embarrassing enough I have to ask the cashier to speak to them to verify its me. Unacceptable. I have family and friends who have 5 times my limit and swipe 3 times more than me and they do not have these problems. Feels like I am being victimizes and set up for embarrassment.
