Sounds very much like he's regretting spending his money!
When I'm buying or selling guitars, I don't think I'll trust delivery to any courier company any more. I've had strats go missing for 6 weeks and turn up back with the seller, all kinds of grief with someone fobbing me off with a Korean strat described as Mexican.
I'll collect in person, they can do the same. If they don't want to travel then the deal's off.
