Bad customer experience at American Swiss

On Saturday I went to American Swiss Westgate to buy earings I was assisted by a lady called Portia I used my credit card to swipe And the lady told me that the slip didn’t print she asked me if I get alerts on my phone I said no but I can view my statements on the absa app I showed her my statement and showed that amount of 399 went through she called her manger nonhlanhla and nonhlanhla told me me that they cannot give me the earrings or the money I can only wait until money for the money to reflect on their side .. I refused to accept that . They then called area manager by the name of tersia who said I must go to the branch to get statesments to prove the amount went through regardless of me showing them my electronic statements I was told to swipe again and if the money is is not in my account I must contact them again on Monday I spent almost an hour in the store And today my money is still not in my account I was double debited for one item
