The only person you should be asking for a refund from is the asshole that you bought this account from.

To expect that the hacked original owner of the account to refund you is just mind boggling to say the least.

How you can sleep at night is a mystery to me as you think it is fine to just screw people and demand that victims should pay you money for trying to screw them.

You really are a piece of shit (and now that it has been noticed don't expect that you'll get away with buying any other accounts here).
