Is the amount large? Forget about less than 3000. If it is too big or uneasy, go to the foreign exchange management counter and make a report with: 1. Description of the situation (that is to say, the reasons for not reporting the expected collection date in time, etc.). ) 2. Copy of the original bank receipt and copy of the original bank declaration form (you can type it in your bank) 3. Fill out a form of export contract and export invoice and register with the foreign exchange management office. He will do it for you. Specifically, you can call again and ask the person in charge of the external management what other materials are needed.
