But if you did, the eBay Money Back Guarantee kicks in.
You open a Dispute as Not As Described.
The first suggestion is to Contact the Seller.
Do NOT get into a conversation.
You want a refund. You are willing to accept the Return Shipping with Confirmation of Delivery before getting the refund.
If the seller doesn't pony up, ask eBay to step in and escalate to a Claim.
If the seller doesn't arrange for return shipping, you win the case and get your refund.
If the seller does arrange for return shipping, when the item shows he has it back, you get your refund.
The tricky bit here, is that if your seller is not in Canada, there is no easy way for him to arrange return shipping.
We can only hope that the new Shippo! shipping service that comes into play soon, will be able to deal with this problem.
