According to the current refund process of online shopping transactions, after the goods received by consumers are inappropriate, disliked or have problems, buyers need to communicate with the merchants to put forward a "refund application", and then deliver the goods to the merchants by express delivery. The merchant can only refund after receiving the return and confirming that it is correct. However, in the process of express delivery to merchants, if there are weather problems and delivery delays, etc. , it will delay the whole refund progress, which is especially difficult for online shopping platforms without special return customer service or direct contact specialists.
