Can I apply for a refund for the only time I go to Tmall?

You can apply for a refund for the only trip to shoot Tmall.

Just notify the seller and explain the reason.

If the order is displayed as "the seller has delivered the goods", if you have received the goods and need to return them, log in to the Baby page I bought from Taobao to find the order, and click Refund/Refund-Refund/Refund. When a refund agreement is reached, it will be displayed as please return the goods.
