I can't see what many are so worried about. It is all working. You open your itinerary from the email that Expedia.ca sent you. Then click where it says "view payment history"
Here is mine:
Delta charge minus the refunded amount is the total that shows on my statement from Expedia.ca. You will see the refund on your charge probably when the Pending charge (mine from Delta) becomes an actual charge.
Nothing is wrong.
No headache.
Good deal. Be happy.
