2. If there is something wrong with the mobile phone for your own reasons and the seller refuses to guarantee it, you should consult the seller about the cost of maintenance. If the cost is too high, please repair it locally.
3. Talk to the seller about the round-trip postage. Generally, if it is not the buyer's fault within 7 days, some sellers can exchange the goods and bear the round-trip postage. This is explained on the seller's website.
Please keep all the chat records with the seller as evidence of Taobao's intervention in future disputes.
5. Please choose a regular courier company. Generally speaking, SF Express and EMS are recommended and insured. Insured price means that your express mail can be insured. Once something is lost or damaged, it will be compensated according to the insured price, which can be foolproof. The general premium is five thousandths, and the thing with 3000 yuan is 15 yuan.
