RCS blocked my card for the second time.

RCS blocked my game store card for the second time. I was buying valentine's day gifts at clicks and when I got to the cashier, my card was declined twice, meaning it is obviously blocked... again. I know this because I checked my statement earlier today, I have R4000 credit available. I had to put everything back and leave, you can imagine my embarrassment... thanks a lot RCS. You don't have to unblock my card, I'm over this nonsense.
