ACKERMANS DOES NOT WANT TO RELEASE MY LAY-BUY AFTER I PAID FOR IT... NO REFUND AS WELL

Last week Thursday I want to pay for my Lay-buy at Ackermans Centurion Mall. I swiped my card but they refused to give me my package as they claim that my payment is not reflecting on their system. I have done everything that they have asked me from my bank statements to show that the payment paid to their account. everyday they tell me to come back the next day. it's been almost a week now, going back and forth. They took R400+ for my payment and I'm still sitting with no goods... what the he'll is this?
