What do you mean, the order has been completed and you can't continue to send messages?

A: The message cannot be sent after the order is completed, which means that the transaction of the order can no longer be completed and the order is closed. This situation may exist because the buyer cancels the order voluntarily for personal reasons, or the seller cancels the order voluntarily. When shopping on Taobao, once the buyer submits an order, Taobao system will automatically generate an order number. If the buyer fails to pay, the overdue order will be automatically closed and the transaction cannot continue.
