Start with a polite note to the seller asking some random question. Perhaps if she will be sending by USPS and noting that it now includes Delivery Confirmation to Canada.
Once you have communication opened and on a pleasant basis, you can move on.
The seller may have realized that giving 10 minutes (!!!!) to pay was silly. She may have pulled the auction because she realized you had already bought it.
Assume the best.
But prepare for the worst. You have up to 60 days to leave feedback. The most effective feedback is calm and factual. At the same time you can leave Detailed Seller Ratings, including on Description (Ten Minutes!!!) and Communication. The normal rating is five stars, the lowest is ONE star.
