Doubtful. If they were on the bill that you were presented before handing over your card, you're assumed to have read and accepted the charges before payment. The only exception would be if it was misrepresented as a tip, or tax (Telcos used to do that one, phrasing their fees as taxes, to the point that "you are not allowed to call a charge a tax unless that charge in its entirety is going to a governmental entity").
