Question regarding a deal

So I traded a stat account for an @.
Deal went smooth, this was yesteday.
Well today he told me the old owner is pulling the account back. He claimed to have secured it but he never even changed the FB attached to it. He still has access but they can both take the account whevever they want. He thinks its my fault so he wants the @ back and he'll give me the account. Though he lost 1k+ followers on it.
So my question is - is it my fault? Should he get the @ back even though HE lost the account? please help me out guys.

IT IS COMPLETELY YOUR FAULT WHAT ARE YOU TALKING ABOUT!
You don't sell something that can be taken back. You cannot unhook someone else's Facebook from an account.

If the account got pulled back and you're the one that sold it to him I do believe that you should give him his @ back to him. If the OG owner you bought it from pulled it back then imo it's kinda fucked that so idk man. I think you should give it back but that's just my personal opinion.

Even though he is banned on here, reimburse him. You fucked him in the ass with that deal as he kept bugging me about getting him his first stat page.
