My Refund still not paid

I swiped my bank card to pay for goods purchased on 17/01/2016, the cashier gave me a slip that the payment was cancelled. The branch manager came up, and said it was my banks problem. The funds have been deducted from my bank account. I had a number Pick & Pay personnel that called me about this problem on 19/01/2016, since then I had no feed back or my money paid back to me. CAN PICK & PAY DIRECTORS PLEASE CONTACT ME, THIS IS SO DISCUSTING FOR SUCH A LARGE COMPANY NOT REFUND ITS CUSTOMERS. NO MORE SHOPPING AT PICK & PAY, THEY CAN KEEP MY MONEY.
