Bought Account #6, Owner recovered. He has been in contact with me and I have control of the account again, however he has still not removed the email or forwarded the code from Jagex allowing me to do so though I have asked him to.
I hope to edit this and have a happy update, but I can not use the account while he can recover.
Edit: Talking with OP about this, he is continuing to be polite and I hope to have everything worked out soon.
