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.

This number has been calling me daily for weeks, but I dont anser unknown numbers due to past experinces
Constant calls with no response
If I don't recognize the caller, I immediately delete the number without answering
When my mom first answered, a woman with a Småland dialect claimed to be from SIFO, conducting a survey about youngsters' opinions, but I'm unsure what it was about; she asked for the youngest family member who had recently turned 15, which would be me, and my mom told her I wasn't home, then the next time they called, my mom said I was busy studying, and tonight my dad answered, but they just hung up on him, so something fishy is going on
