I hope everything is on the up and up as well as everyone else but since we are all blind to the facts it is a must to start pushing to get things like this solved. It is human nature to mount a defense when accused innocent or guilty BUT in the correspondence we can glean the facts most of the time. The simple fact is that you have the check and he has no converter(he says) so the burden of proof is on you 572. The tracking number would have told you to that the converter was delivered and what time and who signed for it. As a matter of fact, I didnt know you could ship anythng without one! It would be a protection for you as much as him.
