Unexplained charges by NEDBANK after new card

I'd like to know why all of a sudden i'm being charged a fee by nedbank for buying items in foreign currency, namely USD. When i had the VISA card i used to buy many items on a weekly basis without a separate debit amount of a percentage paid going off my account. Every since receiving a new card which now has Maestro which i did not ask for I'm getting charged for every transaction under INT CURRENCY C***. <br> If this is linked to Maestro then please may i have a VISA replacement and not the card that was given to me. No where did i agree to these terms. Just to add, the call centre agentrs are ill informed of your products hence logging a complaint here as no one replies to emails as well . Please may this be resolved in either a full explanation or a VISA card replacement if transactions are linked to the account type. I do not want to have to move to another bank just so i may continue online shopping without being ********** by a bank. No other bank charges for these and only recently i'm being charged by Nedbank. I refuse to be charged for every single item i purchase online.
