unable to purchase item

Good Morning,<br> <br> On Sunday the 13th December 2015, I went to the Coricraft in Richards Bay, I wanted to purchase a carpet, I presented the ladies (manager and assistant) with my yellow store card to pay. I was told my card had expired, I rep**** and said it is impossible as my account is still active, they then phoned head office and was told that their store cards (Coricraft was not active yet) hence I could not purchase. I was then told that they would try swipe on another atm machine, and they had no idea how to go on further with the transaction. I was then told it is the first time they had seen the yellow store card
