Dubble charged

On 27 Feb 2015 we ate at Ocean Basket (Monte Casino). The training waiter Desmond Tichawangana swiped our card for payment, but did not register on their system. I received a sms that the payment did went through. He called his manager Lazarus and he demanded to swipe the card again. Then I received another sms for the same payment. I called Lazarus several times already, but no refund till now. The amount was R325.00
