Nothing, you can go to the court to complain about the company that issued the loan, issue the loan without confirming yourself, and issue strong evidence, autograph, fingerprint or audio-visual screen to prove that the lender is you. If you can't prove it, borrowing money is illegal. Don't panic, you will win the case through legal procedures. Finally, remember to ask the losing party for all kinds of damages and apologize and sue your lawyer's fees. Lenders may make various threats, so remember to call the police and inform your family in time. Don't bother to go through legal procedures, because it's no use talking to the lender.
