Bad Service

On the 25th i used my card to purchase from Ackermans Wonder park, i first used the speed point teller and they told me that the payment didn't go through but received an sms showing that it did go through. Then the lady that was helping me asked me to use the main teller next to her which was operated by Pinkie, then again i received the sms showing that i have made another purchase from Ackermans for the same amount. On monday i phoned the bank and they confirmed that i did made 2 transaction at Ackermans for the same amount.On Tuesday the 27th i then phoned the store manager explained the whole story to him and he said he will try and check why one transaction was not returned by the bank and promised to come back to me with the feedback. Still today the bank hasn't returned my money and Ackermans hasn't phoned me yet.
