Being curious about a call I recieved, I participated in a 'survey' from over the phone (different number)

Today I 'Won' a set of knives or a trip for 2 for 3 nights from this number that called me back. It's of course a scam, and should be covered by the CRTC Do-Not-Call list.

I am reporting them now.

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.

Came in as "unknown name/unknown number" (I googled to find this).  Yep, SPT from Manilla, couldn't tell me what SPT stands for, said the website was SPT.com (redirects to an unrelated insurance site), didn't speak English beyond his script, got confused and hung up.  Whatever.  They've learned that the Do No Call list doesn't apply to surveys, so they're claiming to do one to get their foot in the door, so to speak.

I just got a call from a blocked number. The caller (female) said she was with "SPT" conducting an environmental survey.I asked her what SPT stands for and she said it doesn't stand for anything.I asked her what kind of work they do and she said they conduct enviormental studies for Canadian companies.I asked her if she could give me some examples of companies that they work with and she replied, "No I can't, because we don't have any regular clients."I asked her where their headquarters were located and she said "Manila."I asked her if they have any locations in Canada and she said "no."I asked her if they do any work outside of Canada and she said "no." (Aside: yet they have no locations in Canada?)I asked her what the address of their location in Manila was, and she said, "It's in Manila, sir."I asked her if they have a website and she said "just search for SPT." I asked her if they had a URL and she said, "to be honest, sir, we do not."Honestly would have been appreciated from the start, not only after she was pressed for answers. Anyways, definite scam.

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

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