i had a $22.00 long distance charge on my bill, month before last, to Toronto. i know exactly two people, well enough to call them, in Canada and they both live in Montreal. \
AND, as you mentioned, it was at a totally weird hour. like 3:15 a.m.i paid the bill and deducted that charge and called SBC/AT&T.....
and i recently found that i was being charged twice for a "special" tax in Texas.......
it pays to go over the bill with a fine tooth comb. everyone that doesn't, just puts money in the corporate pocket.....
