I got this call today and I think this is who they arehttp://sptbusiness.com/index.html

On checking further, I found this 2010 decision by the CRTC against a company (Breathe E-Z Homes Ltd.) who used SPT to do surveys just like this (http://www.crtc.gc.ca/eng/archive/2010/2010-572.htm). They got people to agree (or not disagree) to a followup if they won a prize, but they sold that phone list to a company who then used it to target consumers (thus telemarketing, even to people on the DNC). They were fined the ridiculously low sum of $2,000, and either they or another company must have decided it's worth that little bit to try it again. (The website for SPT given in the footnotes no longer exists.)

Have gotten a few calls about an "environmental survey."  I asked for the company name, she said SPT, her name was Trixie.  When I asked for the number that she's calling from she gave me my own number.  I said, "that's my phone number, I would like the number YOU are calling from please.  She then hung up on me.

Had 2 calls now from this company, SPT Environmental Research, Heather from (604) 998-8841.  Answered her basic questions, however, when she asked my profession i answered Prostitute, my husband is a Mercenary and kills people, although he only works part-time!  She said we sound like a hard working couple and should be proud!?!?!?  Obviously her english skills only pertain to the script she is reading!  Told her i didn't want her "prize" and please remove me from call list as i am on do not call list.  She responded that they are  a research company and not telemarketer. Another one for call-block.

Same thing happened to me this eve. The man with an accent I couldn't recognize zoomed through a series of questions:
Do I smoke, if I was married, where I work, how long I worked there, if I recycle, my first name etc.
When I insisted he give me the name of the firm he was calling from he said he was from "SPT Demographic Research." I googled this name, but it brings up a number of different pages, so I'm not sure which it is or if it is even one of them.
When I asked what the firm's phone number was, he said it was (403) 648-2643. I called this number, but it comes up as a number that doesn't exist. But the area code is an Oklahoma area code. Interesting considering I live in Canada.
How do I report this scam?

Had a survey questionnaire asking about clean air quality.  The caller (female) said she was calling from the Phillipines.  She represented the SPT Research Company for air qualiaty.  The number to call back was (403) 648-2643.  She said I may have won something for answering the questions and will notify me later.   When I called the number somebody answered who couldn't peak English and hung up on me.    I called twice.  Same thing happened.I answered her questions with vague answers.  She had no idea what the company's full name stood for - SPT when I asked her. How do I report this scam?
