Hello!
I have just encountered the same issue. I paid them 300.00 and they stopped replying back to my emails. I should've researched it before I sent the money. You can file a complaint at

The guy I was talking to stated that he was in Vancouver, BC but the money went to Italy. The guy provided me with the wrong address coz it was picked up at a different western union location.
I'm so mad at myself for not researching it first. I called the phone # today and the # on their web site is just a fax dial tone.
FYI - Western Union doesn't need the sellers address. As long as you give them the country and the guy's name, the guy can then pick it up at any western union location (if he's expecting money).
