Suggestion:
1. Standardize the submission of receiving information, including streets, roads and specific receiving addresses of provinces, cities and counties. The receiving information should be as complete as possible, otherwise the courier will not receive it or deliver it.
2. After submission, send a private message to the lottery headline number to remind him to deliver the goods, and also leave evidence. If he doesn't respond, it's convenient to complain about him later.
3. Contact the headline number: the headline number administrator or the national lottery and complain about him.
Most people will mail prizes, but after all, a few people won't. Originally, the official lottery was a good thing, which brought interaction to the sponsors and participants, and they were all very happy. However, it is inevitable that a few people don't obey the rules and must complain and punish them, so they can't encourage this bad habit.
