If the seller fails to deliver the goods on the agreed time, you can log in to [My Taobao] - [Purchased Products] on your computer within 15 days after the order transaction is closed, find the order, click [Complain to Seller], select the specific reason for the complaint [Failed to deliver the goods on the agreed time], and initiate a complaint. Failure to deliver the goods at the agreed time includes but is not limited to the following situations:

1. After the buyer has paid, the seller fails to deliver the goods at the agreed time (if the buyer and the seller have no agreement, the seller must deliver the goods within seventy-two hours after the buyer has paid; if the delivery time is agreed upon by the seller, the seller must deliver the goods within the promised time after the buyer has paid; if the seller joins an official event, the agreed delivery time shall be based on the time required by the event.

After the courier company completes entering the information on the courier order into the courier company system, Taobao's cooperative logistics will synchronize this information to Taobao.com, and the buyer can view it in "Purchased Products".)

2. After the buyer has paid, the seller claims that the goods are defective or out of stock, causing the buyer to apply for a refund, so that the seller is actually unable to deliver the goods within the agreed delivery time;

3. After the buyer has paid, the seller unilaterally refuses to deliver or suspends delivery (such as recalling goods that have been sent but not delivered without authorization) for its own reasons (such as worrying about receiving a medium or bad review later);

4. The seller clicks the "ship" button but does not actually ship the goods within the agreed delivery time; the seller's delivery time shall be based on the time recorded in the courier company's system.
