I am writing to formally request that you immediately cease and desist all forms of unwanted communications to me, including but not limited to: phone calls, emails, text messages, letters, and other direct or indirect contact.
Your persistent communications are unwanted, unwelcome, and are causing disturbance. If you do not stop these actions, I will consider seeking all available legal remedies.
This letter serves as official notice for you to stop all unwanted communications with immediate effect. Retain this letter for your records.
If you continue to disregard this request, I may take further action as permitted by law.
