They're calling me for a long time and whenever i answered the call no reply coming from the other side

This number annoys me a lot every day... even after hanging up, it keeps calling. i don’t understand how to block.. how can i get out of this problem... what do you do the call will not come.

This call seems to annoy me, now I don't get what I need, so I get annoyed and don't answer.

very distrup me
