Hey Zhang, thank you for taking the time to explain the situation - it's appreciated.
Maybe you can tell to your agent that this is important hardware, and that it is crucial to have tracking numbers the same day the packages are handled to DHL? They should be able to do that, even if it is likely to be an additional cost as it requires some manual work. But the cost of potential stolen packages because of thieves exploiting this vulnerability it's likely to be much higher, please consider that.
Just an idea to try to make everybody safer.
Please reread what zhang wrote and read between the lines this time. The Chinese mafia doesn't care if you get your money-printing machine now or never, the Chinese mafia is also not interested in customer service ratings, the Chinese mafia just provides a convenient relayment service between Bitsyncom and DHL. Bitsyncom can take it or leave it. Trying to tell the Chinese mafia how to do their job usually ends badly.
Don't know if that kind of attitude will help to solve a problem we are having, both Avalon and its customers.
But anyhow its possible that Avalon's agent (name it as you wish) could provide that service for an incremental cost.
