These calls are clearly spam attempts that masquerade as official verification, often demanding personal status like S Pass, EP, or citizenship. The abrupt hang‑up when you push back is a classic red flag. To protect yourself, never share personal identifiers over an unsolicited call, and consider blocking the number or registering it with your carrier’s spam‑filter service. If the call claims to be from a government agency, request a callback on an official number you locate independently. Keep a log of suspicious calls and report persistent offenders to the relevant consumer protection authority. Staying cautious and verifying sources will keep your data safe.
The caller asked whether I hold an S Pass, EP, or citizenship, and hung up when I asked why the information was needed.
