How to contact customer service when buying a mobile phone in Xiaomi Mall? I don't know when they will deliver the goods and what express delivery.

On the APP side of Xiaomi Mall, click Service ~ My Service ~ Contact Customer Service ~ 24-hour online customer service ~ to open the dialog box. Attention, this is the Tu Ami robot. Click the icon with headphones in the upper right corner of the chat interface. After the customer service is connected, tell him the order number or the receiving mobile phone number, let her have a look or urge it, and basically there will be no result. Spot delivery within 7 days, mobile phone orders sent to the nearest warehouse. Generally, most of the express mail in Shanghai warehouse is distributed to SF, while most of the warehouses in Shenzhen are selected as Fengda, and the warehouse in Beijing is SF, such as Fengda, and EMS is random.
