Why didn't Unicom send a text message to remind you to deduct the fee?

This is Unicom's practice, which is to cheat money inexplicably. I won't check it for you when I go to the online business hall. I will keep calling 100 10 to tell you that it is the rush hour. In fact, I don't want people to get through at all. If the traffic exceeds, I won't tell the user, so I can trick the user into deducting more money. The most shameless thing is that I called on May 1 day to say that it was opened on June 1 day, but I couldn't get through to this customer service on April 30. Let all Unicom customers feel cold, Unicom has no future.
