Sifo survey calls – how to stop the annoyance!
Summary — +4645728005
Expert Opinion
Clearly, these calls are most likely from a market research firm conducting surveys. Recipients report frequent, often daily, attempts to reach them for opinion polls, typically identified as Sifo or TNS Sifo. While such research is legitimate, the volume can become intrusive. Block the number on your handset and consider adding it to any national do‑not‑call registry. Request that Sifo place your details on their internal suppression list for a minimum of ten years, as some users have successfully done. Remain cautious of any unexpected requests for personal data or payments, as genuine surveys will never ask for money. Register your preference and keep a log of unwanted calls to help future complaints.
