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.

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 that one too spt or something Askin if I was  house owner had pets if was a smoker I

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.

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?

I got the same call, and was seriously annoyed!!  He said it was for an environmental survey for my city.  When he asked me all these random questions pissed and asked to speak to a supervisor and of coarse there wasn't one to talk to. I asked for the number to the office and the number he gave me was (403) 648-2643 I asked him where he was calling from and he said the Phillipenes.(sp?).....lol  I told them under no circumstances were they to contact me with a "prize" that I may win, which I obviously know it's just going to be to sell me stuff.  Don't waste your time on the "survey"
