Pick n Pay card complaint

Good day.

I have a Pick 'n Pay card that I swipe with every purchase. It has build up an amount of nearly R100 but when I try to use it, there is a problem with the card and no one can help me to fix it. Not even te managers in store. I have been to 3 Pick 'n Pay stores close to me and no one can assist me in store. I have phoned your "customer care" number twice already and they also can't fix the problem. They refer me to the store and the store refers me back to "customer care".

How is it that no one can assist me? First the problem was that my card is not registered. But when I checked it was registered. Then my ID was used on a different Pick 'n Pay registered card. No idea who used my ID or how that was done. They even gave me a new card in store and transferred my savings amount, but still I cant use it. I even went on the Pick 'n Pay website but also to no success to resolve my problem.

How can it be so difficult to use the money that I build up by supporting Pick 'n Pay? There are loads of stores close to me but still I choose Pick n Pay, but if this problem can't be resolved now I am moving my shopping to a different grocery store.
