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.

Tiresome calls that go unanswered
It is really frustrating when they call at inconvenient times, such as evenings or Saturday lunchtimes, asking to participate in surveys about habits, political interests, and income. The payoff for participating is unclear, but it likely involves future calls to peddle subscriptions and similar unwanted offers.
It's extremely difficult to get rid of them
Persistent caller, ignores responses.
They call me 24/7, cant they juste leave me alowne
The caller hung up immediately after answering
Given the risks of unknown numbers, such as potential fraud and increased calls, it's best not to answer; this principle is key in today's society where mobile scams are prevalent

A Sifo survey to avoid, they often call at inconvenient hours
