If you look at the skype you spoke with, it clearly says:
live.won_gold5581
the correct skype is:
live:won_gold5581
Notice how the colon ( : ) is replaced by a dot ( . )
Also, in the PM won is confirming the skype he was talking to, which was egrsbot. I'm presuming that is not your skype, considering you spoke with an impostor. For the future, when a user PMs you saying "you skype is xxxxxxx" that means they are speaking with that skype.
