I have reservations about this story. That said, if it were true.
You need to assume that all that money is lost, quickly tie up any possibility of further loss, swap accounts, passwords to everything.
Then decide if you distance yourself entirely, or seek services to compensate your losses, expecting them to require more cash, but supply longer/further services for that. If you ask them to work it off without any further payment, they will walk away from the dead cash cow.
These girls only work for the cash, irrelevant to race, creed, colour or level of service they offer.
