Sucks
Lil, I seen you around and I am on your side as far as I think he is f'ing with you and trying to scam ya. Having said that, I'd be pissed if you sent me a transponder in an envelope, with the way packages are tossed around and look like they have been through war.
Sure as hell doesnt give him the right to rip you off, hope it goes well for ya mate!
