1. should be avoided in the future (key).
2. Try to pay with white bars and small coffers (it is best to save hundreds of dollars), and it is best to support a company's new products (let it think that you are a quality user and an ordinary user).
3. Place an order on the mobile terminal.
4. Try to mention as little as possible. If you don't mention it, don't mention it (you really can't open PLUS, a month's free coupon is enough to spend, which will increase your reputation).
5. Try to do small and large transactions to avoid day trading (an owner mistakenly thinks that you place an order maliciously).
6. Contact customer service (the supervisor is the best, and you told him that you can't get the link to the coupon). I heard that this netizen chatted with customer service every day for a month-this move is also effective, and I plan to introduce a certain whitening method in the next article.
7. Remember to bill (key)-don't be greedy for free billing or using coupons. If you use it too much, close the little black room.
If the above methods of washing black numbers are ineffective, only one can be re-registered.
