Dischem dire disappointment

Today I tried to shop at dischem to use up the credit I put on my student child’s account (no longer a student away from home). I was honest and said it was my son’s card, I just needed to clear the credit. The cashier told me I shouldn’t have told her it was my son’s card and that I couldn’t use the card (basically if I’d just shut up I could have used it). I showed her paperwork of me setting up the account and the bank pop to prove the authenticity. They were very rude and refused to let me use the card. In a rage, I left. I tried 30 min later at another dischem, only to find out that the store manager had blocked his card and reported it ******. REALLY? My son, my money. Now mom is accused of *****ing her own son’s dischem card. Get a life, Dischem Marine Walk. You’ll never see me on your store again. Pathetic (btw - it was face wash for MY son). I will visit a different dischem now, with son in tow, void and throw away the original plastic card, to be produced with a different plastic card, once credit is spent, will throw away said card. Lovely for the environment (and my mood😡).
