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.
There have been an overwhelming 20 calls from this number over the weekend
If this is indeed SIFO, why are they calling from a 0457 number when they normally use 010 numbers for their surveys
Received a call past 20:00, which is well after business hours...they will eventually give up...;-)
Jag fick ett kort samtal, men ingen klar anledning till varför de ringde.
The constant calls are annoying and frustrating; it can't be enjoyable to have a job like that
It seems they're not very bright as they're calling our office on weekends, but at least I avoid talking to them; going to block them for security reasons
An unwanted call was received late in the evening, presumably from SIFO, at an inconvenient time
Such a pesky person, kept asking me alot of questions
The calls from this number persist even if you don't answer
Totaly useless, wont stop calling
Numret svarade snabbt, okej service.
Following recieveing severl calls from this number over severl weeks, it becames aparent that it is Sifo, a companey that has been contacing me regualrly. A woman carefuly introdused herself, stating she was from Sifo Ronneby, and I would recomend answeing, as they will persist untill you do. They enquire about my radio listning habbits
Excellent experience with Seko's survey!
044728005 döpte mig till en kort förfrågan, men det kändes lite påträngande.
The frequency of calls, sometimes up to 10 times a day, every day, is overwhelming and occurs at both convenient and inconvenient times.
They wanted me to respond to certain questions
They keep calling despite promises to stop
Its just Sifo, for gods sake why peoples gets so upset
Harassing phone calls reported
I received two annoying calls today 😠
Obvious scam, didnt bother anspering the suspicious call
Salesperson who would not accept rejection, spoke in English and was harassing
They keep calling all the time, but i dont answer it
I dont anser calls from unknown numbers
Why do they call when you're asleep?
Constant calls are being made, it's harassment!
Multiple calls were made, but no one spoke when I answered, it seems they do not comprehend the lack of interest
They ask for participation in a survey.
This number have call me 4 times in one evening, its harrassment
No clue who's calling, as I never answer unknown numbers and have added this one to my block list. The calls persist at odd hours, which is surprising if it's indeed a reputable company like SIFO.
