How to remove event listeners?

Question

JavaScript

There is, for example, the following code.

class Account {
    constructor(data) {
        this.user = new User();
        this.registerEvents();
        this.logOn({login: this.user.login, password: this.user.password});
        return this;
    }

    registerEvents() {
        this.user.on('loggedOn', () => {
            console.log('Login success!');
        })
        
        this.user.on('friendList', () => {
            //... -- обработал данные, и хочу завершить работу
            this.destruction();
        })

    }    

    logOn(data) {
        this.user.logOn(data);
    }

    destruction() {
        this.user.removeAllListeners();
        this.user.logOff();
        this.user = null;
    }
}

The problem is that after the destruction(); The software is still listening to events.
Yes, I understand - you can use not .on() but .once() but sometimes it happens that I need to process the data several times.
How to clear the class in general, so that there are no leaks?
