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?

Just got the same call over two nights. Before giving any info I asked for their number and Clarice said I was entered into a draw on september 17 for $500 for any store!!!!  They also said I won either a trip for two or a Slapchop. I said I would take the slapchop and she said that's great ... Its what most people take!!!!  Anyways I got their number and she said her company was Meditech group which was weird cuz the survey yesterday was about recycling.  Anyways I have no intention of calling back but thought I would still report it

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.

Ugh. I just got the same call as Margaret in Winnipeg. It seemed harmless to me - questions about pets, recycling, own your home...I was rude to him the whole time, but I played along with his questions. I can't wait to see if I win the daily prize...NOT.

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