What should I do if I receive a harassing message and it is close to the leader's mobile phone number?

You should blacklist the mobile phone numbers that receive harassing text messages, so as not to disturb your life. Once you received a harassing message, which was very similar to the leader's mobile phone number and thought it was sent by the leader. Its content is very vulgar. You called the leader and scolded him. After reading it carefully, you realize that you have made a mistake. The next day, you quickly apologize to the leader and explain the reasons.
