You can copy the buyer's account name, then use the Taobao Want Want function to add friends, enter the account name, click Search, then check the business card or information, then open his favorites or TaoJianghu, and then click his Want Want icon to contact him.
With this trick, you may find many fake buyers, and many of them are credit.
I suggest you ask the seller directly. If the seller gives you false information, you can return it or make complaints or bad reviews.
