Got a call this afternoon from this number. A nice kid named Casey asked me questions about how I planned on voting in the elections this year. Being very outspoken and opinionated I told him everything he wanted to know. I guess he felt the same way because we had some good laughs. I don't mind helping them out. These surveys help us all out. And no, surveys and charities do not have to abide by the Do Not Call registry rules. It's voting season. Better get used to them.

Called at 9:45 pm. Immediately apologized for calling so late! Asked for female head of household. Asked if she had to apologize, why calling so late? Her response was "just doing my job" and it is impossible for her to remove my name from the calling list.

Call came in at 9:44pm. I had to say "hello" twice before someone actually spoke. when she did, she stated her name, that she was calling for Key Research and was she speaking with the head of the household. I told her yes and that it was a quarter to ten at night! She apologized and further stated that they are calling at all different hours to catch people on different work schedules. I told her "um-NO". She bid me a good night and hung up. Thankfully, the phone ringing so late did not wake up my sleeping children!

Received a five second no speaking voicemail, it sounded like the call-center typing/voices in the background and then a click hangup from CID: Utah, Ph# 801-377-7003 @ 6:13 PM, 2013 July 01. If this is a USA survey company why are they calling me in BC Canada?

Some kind of survey. They're in Utah. I'm in Michigan. I told them, "I don't participate in surveys." Hopefully, that will be the end of it.

Same number called and identified themselves as KCS and were doing a radio station survey. "For the purpose of categorising can we have your age?"
Told them "I don't wish to participate."
They said "Thank you" and hung up.
I then blocked their number.
I am on the Canadian DNC List, and these lists do not extend across the borders.
I would like to know why a company in Utah is interested in what radio station I listen to in Canada.

Smells like a scheme. I suspect they are trying to mine personal information.
