Worst Service experienced from Truworths Fourways

Purchased items on the Truworths account at Truworths Fourways mall. But because the limit exceeded more than the limit, head office had to be phoned to approve the purchase. During the call, the teller walked away because of bad reception. When he returned, he said it was approved and we went on our way with the purchase.

Next day we had some items to exchange due to sizing but was told the card was blocked due to the fact the call from yesterday dropped. So today we could not exchange the clothing or unblock the card because there was no one to assist with that service.

How do you approve the transaction and then give us the close and in the same action block the card????!!!!! How do you have these policy in place but no solution as to solve and everyone including the manager shrugs their shoulders?

This is absolutely the worst service I have ever experienced from a retailer. The customer service is non existing. Do not buy items on your account as they have no clue as to how their policy works!!
