This is wrong. Totally wrong. I need a followup from GP or I will also drop Hyatt like a rock...
I think you need to call U.S. GP and file a formal complaint. I know the Aussies come up with some strange RC rules off the cuff but this one takes the cake. Please be sure to add that they told you that there would be a $90 charge and dropped it to $30 but like you said $5 is too much.
