Acknowledging that the company is legitimate, they nevertheless keep ringing me. I request removal from their list, they claim to comply, yet after four months the calls resume. I want the calls to cease.
Please be aware that this number belongs to Ipsos and is genuine; their office hours run from 9 am to 9 pm, which explains the late‑night calls. I spoke with a very courteous gentleman today who said the call relates to an HMRC savings scheme. Check your email for a corresponding message, especially if the call comes after normal working hours. I can confirm the survey is legitimate, informative and worth taking, but note that scammers also use this number. You can spot them by asking for their FCA or company registration number – refusal means it’s a scam.
After several calls this week (starting 21.01.25) I finally answered as they seemed to stop calling. I told them they were scammers and they responded by offering their customer service number for Ipsos. If you prefer to take part by phone, please email Ipsos at
This number persistenly calls me outside of working hours, yet never bothers to leave a voicemail, completly baffled as to how they aquired my number, and they only ring between 7:00pm and 10:30pm, at absolutly rediculous oclock!!
Called at 8:30 PM. Didn't answer. Checked online and saw others reporting similar calls. Seems to be a scam claiming to be from a government questionnaire team. Block immediately.
