it's very simple, I immediately understood your intentions and tried to take some action, I've already heard about stories about frauds when you buy an account and it can be tried in a dishonest way through the tied address of bitcoin to pick up, but unfortunately did not give it a value before.
but now I understand that I ran into a typical swindler
So didn't you take any precautions before the account ? Did they provide you signed messages before buying an account ? Who contacted first on bitcointalk about the account sale ? I'm pretty sure you would have messaged them on bitcointalk first,if so which was the profile involved ? And stop ignoring my questions,the account is useless now anyway.
