What if JD.COM customer service can't read it back?

JD。 The customer service of COM shows that it has been read and does not reply. Basically understood as two situations. You ask him to buy something, display the information you have read but don't reply. That's mostly because the customer service staff is not here and your dialog box is open. Another situation is that you ask him for after-sales service. Most of the reasons are that customers take the time to understand the situation and leave temporarily, and do not rule out the reasons.
