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.

For nearly two months, Springmobil has been calling nonstop, and we are extremely frustrated. Despite contacting them and requesting the name and phone number of the person responsible, the calls continue. A police report will be filed if this harassment does not cease.

4645728005 Unknown Okänd

After discovering this page and seeing numerous reports from others who have been similarly affected, I realized I am not alone in receiving daily calls from this number, often multiple times a day, including weekends and evenings, which is essentially harassment. The problem is, being deaf, I am unable to answer phone calls, which makes it extremely frustrating and disrespectful. This has been ongoing for a while now, so what can be done about it?

This number has called 18 times since January 13th, often multiple times a day, prompting me to silence my phone to avoid disturbance, especially with a young child at home; I've tried looking up the number on eniro and found it belongs to TNS SIFO, so I visited their website at http://www.sifo.research-int.se/ and emailed them to stop calling and reported the numerous missed calls, hoping this resolves the issue

4645728005 Survey Sifo

My mobile received a call, apparently searching for my partner; it's perplexing how they select numbers - if they wish to reach him, they should call his mobile, and if he doesn't answer, it's a clear indication he doesn't want to talk, so there's no need to call me :O However, the caller was polite and mentioned something about removing the number to avoid further calls *-)
