In the event of an error, the bank is not responsible for assisting in recovery. The bank staff suggested that customers should go to the nearest bank counter as soon as possible after discovering the wrong account, and verify the existence of the other party's account with the receipt printed on the day of transfer. If the opposite account does not exist or is invalid, the money will be automatically returned to the sender's account within a certain period of time. However, if the other party's account is true and valid, then the remitter can ask the bank staff to provide the other party's contact information. If the bank is unwilling to provide the personal information of the other party, the remitter should report the case to the public security organ and ask the public security organ to intervene in the investigation. First of all, the public security organ will ask the bank to verify the identity of the other party, and then communicate with the other party whether it is willing to return the money. If the other party refuses to return the money, the remitter can bring a civil lawsuit to the court with the money order, and the court can use the legal provisions of unjust enrichment to help the remitter recover the money. In addition, the remitter can also bring relevant evidence to the local court for pre-litigation preservation. According to the account number and user name provided by the parties, the court seals up the account number in the bank where the payee opens the account, and gets in touch with the other party according to the personal information left by the other party in the bank. If the other party does not admit or is unwilling to return it, the court may enforce it according to the current laws of our country.

About how to deal with it. Keep the transfer record, and then sue for unjust enrichment and return. But there is a problem that needs attention, that is, how to obtain the identity information of the defendant. Although it is now a registration system, many courts still require the plaintiff to provide the defendant's detailed information: name, address and ID number, and provide the defendant's identity certificate: a copy of the ID card or a household registration certificate issued by the police station. For ordinary people, it is difficult to obtain the identity certificate of the defendant. In this case, you need to communicate with the court, can you file a case first, and then ask the bank to cooperate with the investigation and evidence collection after you get the filing documents.
