Report complaints to the local CBRC. If you have any questions or disputes about the loan business, please complain to the local CBRC, which is the competent government agency for all banks and their businesses, regardless of whether the banks are under the responsibility of the police. This kind of bank loan can be said to have more evidence than you, and the result after the loan is nothing more than high interest rate, but generally banks will control it within the scope permitted by law and can only handle it through litigation.
