I often receive phone harassment from EF Education First. Can I call the police?

Of course you can call the police, but I guess the police generally don’t care about this kind of thing. Otherwise, if the phone advertisements are gone, I will teach you a way and they will not call you in the future. If he calls you, it must be you. Where the information you filled in was sold to him, you can tell him that for example, I am a student of EF and I am studying now, and he will not call you next time, or you can say that you are a student of other English training courses. Or you say that I don’t need to learn English now that I’m abroad. In short, if I can’t get any benefits, I won’t give you a fight. Simply saying no doesn’t mean much.
