You should ask whether your bank accepts business in this currency. If you don't accept it, of course you have already returned it. Ask the other party to check whether there is any error in filling in the information. ICBC will return the information directly if it verifies that it is inconsistent. First, you use WeChat to check the bank, which contains the phone number. Then you call the bank directly to ask the specific reason for the return, and you are providing the corresponding information to the other party.
