What should I do if I can't find the invoice number of Debon Logistics?

It is possible that the goods have been sent out but have not been accounted for, so they can't be found. This shows that this company has a bad system. I know that people in Yuancheng Logistics record orders within two hours. I like it very much. You can call their customer service staff now and ask her to tell you about your products. That's all. Answer my question. I'm integrating.
