That is why I'd refuse any delivery from this guy. Or better yet, talk to the Sgt. before doing anything with it. You won't have any way to actually get what you paid for. He is sure to totally disappear after trying to send out some stuff. You could resell it and get some money back if you want. But if you take the stuff then it will probably weaken any case against him (which is what he is trying to do). Since you didn't get what you ordered I'd still talk to the Sgt.
I love how this clown shows up trying to send stuff now and doesn't give a valid return address even though he wants ours. This is all BS.
I've written off getting anything so I'm just fine with letting the police give him what he's earned.
