1 and Taobao's refund mechanism have many problems. Buyers can apply for a refund if they don't receive the goods. But you can't get the money directly yet. Only after seven days of friendly negotiation can you get the money. You should know that if you don't receive the goods, the buyer's rights have been violated (such as a time-sensitive transaction, which may be a Christmas gift or a friend's wedding gift, but the delay in receiving the goods will cause great losses to the buyer), but it is actually impossible to negotiate amicably.
2. Taobao Mall lacks a good and bad comment mechanism, just letting buyers score. So you can't see the service level of a seller. Because most of the average scores are around 4.5.
