Update (19th April 2013) - I'm still getting spam despite being assured that it will stop - read more.
Yesterday I posted about my experiences with ICM and an affiliated website, newvistalive.com. In it I explained how I had repeatedly tried to unsubscribe from their email survey service to no effect, I also included the text of an email I'd written to Keith Bates, apparently the head of the 'Insight Division' of Creston, the overarching company that controls ICM, newvista Research and many others.
I waxed lyrical about how I didn't expect to receive any response to this email, but I was wrong.
Last night I received this response:
Dear Mr Zoltan,
I was very concerned to receive your email and immediately launched an investigation into your case. My team have been working on this matter for the past few hours and I am now in a position to respond to you
Firstly, let me apologize for the experience you have suffered. This is far below our usual standard. Secondly, I would like to reassure you that normally panellists cannot receive a survey until they have logged in, with login and password details being issued upon first registration. This evening we have double checked our procedures and are satisfied that all are operating properly.
Finally, I can confirm that you have been unsubscribed from our panel and that you will not hear from us again.
I am sorry that you have experienced a less than satisfactory level of service and hope that this will not affect your future participation in market research surveys.
So it would appear that my ranting might just have achieved something for once.
It's just a shame that it took such drastic action to get the desired result!
