How to complain about Lexun online sellers?

Music news. com！ ! I didn't expect you to buy it on this little-known website, but I have been online for so many years and I have no impression at all. . . Is it that its advertising is not successful enough, or am I really ignorant! If you encounter such a problem, if you are on C2C websites such as Taobao and Paipai, you can take screenshots of your chat records. Of course, there are clear ways to deal with these problems after sale, or they are described in the product details. If it is a three-package store, what is the specific time limit for return and warranty? If it is within the time limit, you can also check the logistics information at that time, when to confirm the receipt, the vouchers you sent back, etc., and upload these screenshots to the website. At that time, I forgot what I bought on Paipai. I was cheated for more than 30 yuan and got it back. The rule of thumb is to look at the buyer's evaluation. Basically, if more than three people can't say it well, don't buy it! Don't listen to the seller's lies before placing an order!
