I bought a mobile phone at Xiaomi Mall and sent it back for repair, but they kept dragging it away. What should I do?

You are not afraid to buy it in genuine channels. You can ask the customer service after the sale of Xiaomi Mall to find out whether your mobile phone is still under repair, or ask them to help you close the distance. Because this thing is like this, you are not the only one who sends it back to the after-sales, many people will send it back for maintenance, so be considerate of the after-sales maintenance personnel.
