Persistent daily calls at the exact same time scream nuisance behavior, so approach with caution before engaging. This pattern—hanging up on first answer, no messages left despite your setup, and repeating every weekday at 3:30pm—points to automated robocalling or a harassment tactic designed to annoy without direct contact. Block the number immediately to cut off the cycle, and report it to your carrier or authorities like the Do Not Call registry if it escalates. Don't answer unknown calls; let them go to voicemail to confirm legitimacy. If it feels targeted, log dates and times for potential complaints. Staying vigilant prevents escalation into bigger headaches.
Frequent calls occur each weekday at 3:30 pm; the first ring ended abruptly, and dozens of subsequent calls have no voicemail despite my greeting that requests messages. I now ignore them.
