I was ****** my change

I went to pick n Pay clothing in east rand mall on Saturday 11/09/2021 @ 13:21 I was exchanging clothes and bought something else. After swiping my smart shopper card ,The cashier (Duduzile P Sibeko)told me I have R40 do I want to use it, I said Yes. Then to my Surprise she only gives me the slip and clothes only , not my change. Then I asked for my change she said its in the card. I said I never said she can put my change in the card , I said She should use the money on the card to pay for the extra clothes then I’ll pay the difference . They told me there is nothing they can do, its there, I can use it to buy anything at Pick ‘n pay. So I had to make a plan to get taxi money since they refused to give me my change back. Then today Monday 13/09/2021 , I decided to go to Carnival Mall to check if that change is there, and buy something with that money, When I get to the till I was told I can’t use that money to pay because the card is not registered. So, I had to pay using cash again. They told me to call customer services so that they can assist me.
