You ignore but you don’t block
You say you don’t want to hear them out but, you do. Over and over again. You give them an opening to speak their piece, and then slam the door in their face. One example is you answer the phone, only to tell them never to call again, and hang up. Then when they call back, you answer again and go through this over and over again. You tell them to stop DMing you, and that you won’t read their messages. But you read each one, and reply saying, “I’m not reading these.” If you really wanted out of the situation, you’d block their phone number, and all of their social media handles. But you do enjoy receiving the groveling messages.
