Update:

I submitted my contestation (is that a word?) of the erroneous tariff charges and everything went....silent.

So, I cheerfully called FedEx. They told me that the feds may not get back to them (and me) for MONTHS!!!!!!! Just my luck, some clerk somewhere makes a mistake in 2.5 seconds and it will now take months to fix. BUT I will save my 4%.....so there!

Is my name Buttle or Tuttle? (old Brasil reference)
