If it helps I used to be a Premier Relationship Assistant when I left Uni, I was able to help folks recover lot funds, one of them - I remember spent shit loads of money not sure why but I noticed a trend seems he won, then thought it's my lucky day after the win I noticed lots of losses - so either his ego kicked in or he was drunk - but whatever the story I wasn't sold. They just have to involve the anti-fraud team, who will try to recover the funds as stated earlier there's also compensation schemes but don't leave it too long, £500 can be easily compensated under the scheme ( there's no playbook for this so check with your bank, policy varies )
This escorts know that most folks are married, so the trick is that you will not want to make a big issue out go it.
The courts are also there, when I was in retail Banking we worked hard to make it difficult to open multiple bank accounts etc as if you close an account due to reported fraud they open another one it was very common among Romanians and Italians because they used ID cards that can be easily replaced, names changed by bribing officials in their home country. Passports are easier to monitor.
It a pain for Banks too Buddy, we just need to make sure that these type of folks don't go back to doing same to others.
I hope you make the right decision, if you do choose to recover your money.
It harder when you login or enter your secret pin and transfer funds, easier when you have no clue what happened.
