i dont know why they keep calling and they need to stop

Someone called from this number and it was concerning my 13-year-old son which is name is (Darien) Stead him and I wanted to know which company and what it is exactly that you need to speak to him with I need you to give me a phone call back as soon as possible after 3 o'clock because I'm at work but I'd appreciate if you let me know because he's a minor and I don't want any companies or anything of that sort trying to reach my child.

I just received a call a few minutes ago and the agent was extremely rude and unprofessional. I offered to take a message, the agent said No!, in a very nasty manner hung up on me.
