-This isn't theft. There was nothing stolen. An open transaction like this is nothing bu t a verbal contract of "you give me this then I'll give you that", which has no legal authority and isn't even remotely close to the act of theft.
it's either theft or fraud. there is likely a chat log on SOMETHING that details an agreement of monetary compensation for the virtual item.
In either instance, it's a crime. ;)
