1. The information received is fraudulent. Some fraudsters will cheat you out of your money by sending false transfer information. If you haven't made the relevant transfer operation, you are probably cheated. I suggest you contact the bank customer service immediately to verify.
2. The information received was caused by someone else's misoperation. Some people will enter the wrong account number or amount during the transfer operation, resulting in the transfer failure, but due to system delay and other reasons, you may receive the other party's transfer information later. If it is determined that this is caused by someone else's misoperation, you can contact the other party for a refund.
The message you received was that your friend or relative transferred money to you. If it is confirmed that the information received is from a friend or relative, it may be that the other party entered the wrong account number during the transfer, which led to the transfer to your account.
