from this situation, it seems that there is suspected contract fraud, so you can ask the transfer contract to be invalid and recover the transfer fee.

Let me tell you what is contract fraud:

Contract fraud is an act of defrauding public and private property by making a contract and taking illegal possession as the purpose, by fabricating facts or concealing the truth. The behavior of contract fraud is manifested in the fact that one party to a contract deliberately fabricates false information, or distorts and covers up the real situation in order to obtain illegal interests, so that the other party falls into a wrong understanding, and therefore makes an expression of intention that is not true, and concludes and performs the contract. The judicial interpretation is "one party intentionally informs the other party of false information, or intentionally conceals the real information to induce the other party to make a wrong expression of intention".
