I just got this call too.  Did anything come from it?  I'm nervous now.

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?

Got tricked! They called and I gave the info they asked for. Had ethnic accent. (woman) Called the next day and it was a very pushy man! I wasn't ready for him! I managed to book an appointment to get my "free" knives and a presentation. I tried to call back---busy signal. I finally found the business name and a reachable phone number! Breathe EZ homes, AKA (403) 214-1446. I called this number and asked them to cancel my appointment and take me off their call list. They were actually polite, probably since I was so irrate. SCAM SCAM SCAM! I wish I knew how they got my number!!

Got a call from that number requesting my information about home and work. Phoned back the next day for my address to give me prize delivered to my door. How should I report?

Got a call Saturday night - I demanded that the caller identify herself by ID number and she refused.  Got angry when I persisted and eventually hung up on me!  Before hanging up she had a man come on the call.  My advice is take control of the conversation and:  1. clearly state to them that the conversation is being recorded and when they acknowledge that then 2.  state that you are registered with the government on the Do Not Call List and that the recording will be forwarded to the government along with their ID/name.  Be persistent about asking for their ID and tell them repeatedly that you want to be taken off their call list and eventually they will hang up on you

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.)
