Imagine the phone buzzing nonstop, each ring a reminder that someone's ignoring your Do Not Call wishes. The pattern points to a persistent telemarketing effort—no voicemail, just relentless repeats. You can file a complaint with the National Do Not Call Registry and your carrier, request a block on the number, and consider a third‑party call‑blocking app. Keep a log of dates and times; that evidence strengthens any report. If the calls persist, escalating to the FTC or your state’s consumer protection office can pressure the source to cease. Staying proactive protects your peace of mind.
