Over charge

As a lifelong client I am disappointed in the poor service rendered by ABSA. I have made a credit card payment for a flight booking to Dreams where the amount shown on website (=-R10450)was relatively lower than the amount authorised by the bank (R11257). I have phoned the private bank call centre which referred me to the ***** department. Neither of them were of any assistance . I have cancelled the transaction with eDreams . The transaction fell under the full refund category because it was cancelled within the required time.(confirmation no :***) I want this amount to be reversed and de-authorised, please! Thanks
