When you need something in a hurry, mail order is not the most efficient way to go.
First ten days is not ten business days and your item could well be in the postal system for 20 calendar days before delivery,
I agree that it is annoying that they are not responding to your eBAy messages nor to your phone call. While usually I would just put it down to a disorganized seller, given the unusual payment instructions and the lack of communication, I would file a Dispute with Paypal as "Item Not Recieved" and ask for the Delivery Confirmation number on your parcel.
Faucets should be bulky enough that Regular Parcel, which is Delivery Confirmed, was used.
If the seller does not give the Confirmation number (which you can trace through canadapost.ca) Paypal will refund your payment. However, (mail order again) there will be a delay to allow the seller to respond.
Don't leave feedback until the situation is resolved. Yoyu have up to 60 days, so stick with the Dispute process. When you do leave feedback you will also be asked to leave Detailed Seller Ratings. The normal Rating left is 5 stars. The lowest Rating is ONE. No rating is a free pass.
