sounds like the guy at the PO was a bit confused
but the package should have still been mailed out ...
shipping to Cananda can take a while sometimes , even though you live close. I wouldnt give up hope just yet. Unfortunately if you cant find the reciept then its going to be a toughie to try and find out where the parcel is (via the customs number) , or to prove that you posted the item, which PO , etc . The buyer has 45 days to make a paypal claim, so you've got a while to go yet . Keep up the good communication with your buyer and see if she will wait a bit longer. If it does get near the paypal deadline and still no parcel, then you'll have to think about either a refund or replacement , even though you will lose money
. Sometimes if its the POs fault and your buyer agreesto it then its fair to go 50/50 and give half refund, but you need to find your receipt for the proof of postage to show your buyer really. I hope it doesnt come to that though and the parcel will arrive soon
