Phone Blizzard, tell them you stopped playing ages ago and can't seem to login, get your account back.
They can revert any Battle.net stuff that has been done if it was a long time ago too.
I know it may seem dishonest but the morons buying accounts absolutely deserve ripping off.
That's interesting to know mate thanks for that. When selling it though I got a phone call from the site that bought it and basically they said they would take legal action if I got the account back. Problem is my character name was changed it was transferred off my account also.
