She bought the Thing.
She paid for the Thing.
You mailed the Thing.
The mail service includes tracking.
The Thing has not yet arrived.
The buyer is an impatient pest.
She cannot open an eBay Dispute (Not Received) until the last estimated date for delivery given by eBay passes.
Has that date passed?
If it has and you cannot prove delivery, you must refund.
If it has not, she cannot open the Dispute.
I don't understand how you have a video recording of a conversation with this person. You should not accept her calls.
Even an old biddy like me knows how Call Display works. When you see her number, don't pick up.
If she emails you, you should recognize her name. Move the unopened email to Archive.
Only respond to eBay Messages but keep your response to" The Thing was mailed on March 15 by Canada Post Expedited Parcel. The tracking number is CAxxxxxxxxx. You can see the last location traced here https://www.canadapost-postescanada.ca/track-reperage/en#/home"
Rinse. Repeat.
EBay will not use any videos as proof of anything. Only Proof of Delivery is used. Never has, never will.
Posting a YT video (which no one will ever see) could, I suppose, leave you open to a suit for slander, but just talking to a lawyer about such a suit, an international one, is going to cost her $300 an hour. So there's that.
But she's a pest.
Oh.
Be prepared for a demand for a refund claiming that the Thing is Not As Described.
Be ready to demand the Return of the Thing before refunding. Even if you have a No Returns policy, you are stil allowed to demand return before refunding. You may have to pay for the return shipping.
What a pest.
