Sounds like a stall tactic, I'd still have put in an escalation with PayPal and not rescinded it until I was satisfied. If it does arrive, I'd take a short video of the un-packaging and inspection as evidence, though a photo should suffice for evidence if it is a replica. Hard to go back now to the terms of service described on the auction, if he stated that delivery would be 15-30 days then at least on that point he has a leg.
