Like a fox slipping through the undergrowth, these unsolicited calls from Ziron slink in at odd hours, peddling vague services tied to heat loss engineers or similar sales pitches. Reports highlight a male voice, possibly AI-generated, making persistent cold calls without leaving voicemails. This pattern screams telemarketing harassment, often relentless and intrusive. To fend them off, block the number immediately, register with the Telephone Preference Service, and never share personal details. If calls escalate, log details and report to Action Fraud—staying vigilant keeps these nuisances at bay.
