I am constantly called by this number and they hang up. On numerous occasions they threatened me. They even stated they would send someone to my residence. I have a small child. They bully and state they will destroy my credit

I keep getting calls at my work place about my son, whom I no longer speak with. I have not contacted him in over 1 year and a half, and would appreciate it if you stop calling. I don't know if there is a number he can be reached at, but again, PLEASE STOP CALLING ME AND MY PLACE OF WORK!!! I am NOT involved in any of his matters.

Thank you,
