Loan scams

They approve my loan and sent me a contact and fee for lawyer they say 2850 after paying they wanted 2550 and when I told them I don't have the money they refused to send it back then I call my bank they try to check if the account I sent to money still has money but it had nothing they advised me to go and open a case at the police station why because the account they gave me it was not a business account but it belongs to someone
