What Coco said. Western Union are probably holding the money.
You did the transfer Friday in aus. They would of held the money over the weekend and done it Tuesday night (mon was a public holiday) that would mean it was what Tuesday in Europe when it went into western union in Europe? So it may of gone into their bank either today or tomorrow you would think with the delays and midnight transfers.
Id trust Attitude. Been fine with me even on a re-send
Why didn't you just do the transfer from your account to theirs?
