If the seller fails to deliver the goods, will the micro-store automatically confirm the order?

That depends on whether the seller has ordered the goods. If you see that the seller has delivered the goods, but you haven't received the goods, or you don't have the logistics information such as the waybill number, you should apply for a return.

Generally speaking, the platform of secured transaction will pay the seller the payment within a period of time after the transaction is successful.

Taobao is 10 days after the seller clicks the delivery. If the buyer does not apply for a refund, the payment will be automatically credited to the seller's account.

Micro-stores should have a similar process, and the time is different at most. Therefore, in the case of delayed confiscation of goods, it is best to apply for a return.

Just checked, the micro store is 7 days.
