insurance over 200.00 expedited from Canada to USA does that meant a signature is automatic?

[foreve-8287]

I sent an item value of 820 from Canada to USA. Paid insurance for 800 expedited and the buyer states they haven't received it but shows delivered on the tracking. Not sure what to do and also with purchasing insurance of 800 doesn't that mean a signature is automatically required? The girl at the post office did all the work as I just showed the address from my phone. I'm stressed out and not sure as I looked to see on the website. Heading to the post office tomorrow but mostly gonna get a run around answer like everything else. The item shows it was received Dec 28th but it's January 19th. Could the buyer be lying about receiving it? Thanks.

This should have been sent with xpresspost usa. No signature for an  $800 sale means ebay will not help you. The buyer will win the case. We are guessing they knew this already before doing the buy.

Its a no cost scam for them to keep trying. If it did arrive and had to sign for then their backup plan is make an item not as described claim and get 100% back that way at the sellers expense. We have had a few like that. Surprised them with ups sig required and that was their response. Stuck with shipping cost both ways and customs dinged us on the way back despite it saying MERCHANDISE RETURN all over it and had to fight that for 2 months. Got it back in the end.
