I don't know people who call, text and curse. Where should I complain about this situation?

Hello, I used to be a mobile terminal, so I want to give you some advice on my work experience. The first is to forward spam messages. If not, you can call 10086 directly. And if you think you are a hooligan, it's not scolding you, to put it bluntly, because I have contacted several cases before, that is, users said they were harassed by others and called to complain. This is because the card you used has been reused. In other words, when someone else used a card and sold it to you, I found you on the phone of the original owner, which caused you harassment. Finally, because we couldn't stand the strong demands of our customers, we changed our customers' numbers. If we want to change a new number, we need your strong complaint. Generally, we won't give you a free replacement unless we can't stand your complaint. It should be useless to call 1 10, because I've been in your situation before, and I was harassed by that pervert. I called the law firm to ask, and they said there was no way to sue. At present, there is no law in China to convict people for insulting language, and 1 10 can't handle it, so please leave her alone. Please 10086 check the list for you, or go online to see if there is any inexplicable deduction. If there is a lot of harassment, you'd better change your card.
