Be wary of filling in a survay from this company

Having completed a survey on the promise of £5 shopping voucher I found that it was impossible to redeem the £5 voucher. This then made me suspicious that this was a scam alleging to be doing a survey for her Majesty’s government money and pension service.

Hi John,

I'm sorry to hear that you've had trouble with your incentive for completing one of our surveys. But, I can assure you that IFF Research is a legitimate, independent UK research agency, and we take any complaints or issues with our surveys seriously.

If you could reach out to us via hello@iffresearch.com, I can then forward on your message to the project team to provide an update and get this sorted for you.

Best wishes,
Matt

Manipulative surveys

I just received yet another communication from this company despite telling them by email that I do not want to take part in any more of their surveys.
I previously told them how unhappy I was that the questions in their survey were structured in such a way as to not allow any alternative viewpoints and skew the results to the obvious conclusion the survey was supposed to come to for their client. Their client was our government, so if that survey was to help inform policy decisions, it clearly was not going to truly represent the electorate. This was clearly nothing more than an exercise to create a digital paper-trail so their client could claim majority support for their policy decisions.
I felt manipulated by having been gulled into completing the first survey and told them as much. I did not want to be part of such deception - not in my name!

To add insult to injury, the promised small bonus for taking part was never forthcoming and when I pointed that out I was told by email to go online and claim it. As it was a measly 5 pounds I couldn't be bothered, but they pestered me by email a few more times to take part in the next phase of their (deceitful) survey which I duly ignored. Now they are sending me letters as well, they clearly cannot understand the word NO.

I will not be part of this dishonourable exercise in misleading the public that we all agree to our tax contributions being used to propagate the suicidal myth of net zero.

Disgusting company

Disgusting company. My mother passed away and they continued to harass me in relation to a repair by my landlord. Awful vile company.
