If I bought something at Tmall Supermarket, I didn't receive it. But it's been a long time. What should I do?

Tmall didn't receive the goods. You should look at the problem first. You can go to the place of purchase to see if the goods have been delivered. If the goods have arrived at the delivery point, sometimes the logistics didn't send you a text message. Check to find out the problem, and then choose how to deal with it according to the situation. If the merchant fails to deliver the goods, contact customer service to ask the reason. If not, apply for a refund.
