So... We "verify", then you say... "I was hacked", and attempt to "get your money back", after having collected "our personal information, in an attempt to verify the account with our credentials", thus, we are then held responsible for every transaction you made on that account... (taxes) from previous transactions...

How about.. you put the funds in escrow, and sell them, for the price you want. You keep your account, and whatever "things" are in the history of your account.
