For us outsiders, this isn't provable either way (though if you really HAD to know you could find out if he'd been racing his Pred at his local club, wherever that is, during his 97 days and counting). It's a situation that other companies avoid however by just sending stuff international signed for. Then it's provable and is one of the cheapest ways of confirming delivery. When it's not it's just someone's word and the company opens itself up for system abuse. Some companies would just bite the bullet whether they believed the customer or not and resend the delivery and some bite another bullet (a lot of bullets here, I'm aware of that) and are prepared to lose a customer that is either a victim of the not 100% postal service or an opportunist con man out to get free stuff.
I have also bitten my own bullet and am posting calmer stuff
