Mokwena is a bad manager with a stinky attitude

I went to Cna forest hill today to buy a xbox360 fifa 16 game. The game is dislayed on the shelf with no price. I took the game to the consultant who was on the counter by the name of Isaiah. He charged the game on my edgars Account. I signed for it and waited to be given the game. A consultant by the name Mpho looked for the game for like 10 minutes before she came back and said she can't find it. Then she called a guy by the name of Mokwena, I think his the manager. He then looked for the game for 15 minutes and could not find it. So had to wait for Isaiah to finish with the customer he was helping , to look for the game as well for like 7 minutes. Then they told they can't find the game. I asked for a reversal, when the refund was being done I was asked to sign for it, then Mokwena said my signature is not the same as the one on the card. I told him it's a different surface am signing on a screen not on a card. Then he said still I told him that this is a refund not a purchase they didn't tell me my signature is not the same as the one on the card on the initial purchase. He said still they have to be same I asked for a card to sign on he refused... I was treated like a ********
