Package was unclaimed?!

today has admittedly not gone like gangbusters so far..
received a message from Candy: the package was returned?!
says it was "unclaimed," which I think is a load of bollocks..
Canada Post didn't deliver it over here in the last weeks..
I should have had a little card indicating undeliverable status..
since I didn't, I assume it was stuck in the postal system..
this is not good news at all.. bad start to the day, of course..
will I get cheered up later on? who knows.. not in a mood now!
