Unicom charges 1983 yuan, which is inexplicably deducted?

This is a charging service customized for users by SP signed by Unicom. As long as you keep calling 100 10 to complain (once a day, no charge anyway), then go to the local Unicom business hall to complain about them every once in a while. Within a month, I promise they will refund your money. Of course, as long as you really don't book this business yourself.
