Bad customer service

Bad customer service I received at jabulani mall makharms they refused to exchange t-shirt for me just because I didn't have account card that was used to purchase the t-shirt,I kindly explained to them the person that bought me t-shirt used their account card and they went away to Mpumalanga for the NEXT 6months meaning I must wait for 6months to do exchange just because I don't have account card with me....this t-shirt was bought as a gift and account was used to purchase it the t-shirt I want to exchange with it's the same value of the original t-shirt....go to Woolworths they kindly exchange or refund you without any stories
