Can a company file a case when conditions wasn’t stated in contract or it’s a scare tactic?

Hi, I met someone by online dating and she turns out to be an escort model for brazzer company. She asked in order to meet her, I have to go thru brazzer booking process. Includes: booking fee, medical examination, finance approval, then there was an error when I send in the payment which I wasn't aware of. Then they asked me to paid for attorney fee to clear up the issue or else they will file a case against me. They promised all the payments will be refundable and all the payments I made is toward their crypto wallets in bitcoins. I panicked and full payment of attorney fee. Then they demanded me to paid for documentation fee and releasing of contract as the final payment and claimed this fee is part of attorney fee, which I wasnt t aware of. Again, they demanded me to paid up full amount ($6000) in 3 days or they will file a case against me. I was blinded sighted every steps, after each payment there was another one. can they really file a case or it’s a scare tactic.
