What if JD.COM's customer service information can't be sent?

Check the phone's network settings to see if there is no network.

If you find that you can't send information to customer service on JD.COM, you need to check the wifi settings of your mobile phone. Or check the traffic of the mobile phone to see if there is no traffic when the mobile phone is stopped. Generally speaking, you can send messages to customers. If it still doesn't work, restart your phone and try again.
