Trying to find who calls from this number.

Claimed to be calling on "behalf of Visa".  When I asked which brand, he said, "any".I immediately told him I was on the Do-Not-Call-List, and told him to add me to their internal do-not-call-list.

Received a call from (905) 327-7829, at around 5:30pm (eastern).  Briefly heard voices on the other end, like you'd hear in a telephone call centre/boiler room.  No one spoke directly to me, although I did say "hello" before there was a click, and the line went silent.  Tried an online reverse phone search on whitepages.  Call came from St. Catherine's-Thorold.  Even had a Google Map showing location (central). Listed as on Bell Mobility network.  Owner's name and address not available via this search method.  Tried a U.S. based reverse cell phone search.  The "free search" gave the same information, but for another $15.00, you are supposed to be able to get a "full report" on the owner's name and location.  Well, I wuz had!! The $15 search told me no more than the free white pages reverse phone search.  Other suggestions for reverse phone searches I found on YouTube include: boardtracker.com, myspace, yourspyingeyes.com.  Type in the full phone number in the search bar.  If no results, try typing in the full number, placing "  " marks around the last 7 digits.  A further aid: try typing in "St. Catherine's-Thorold" after the number, either with or without the area code, "  " marks, etc....
I believe I have some clues as to who may be behind these calls.  I met a strange, large man in Fergus, Ontario, in June of 2008, who claimed to work for Mastercard.  He had been chatting-up my girlfriend for about 3/4 of an hour while we were out at a pub one night with her daughter, listening to music.  When I confronted him, he claimed to have "a job" for my girlfriend, and it included helping him track down $1.5 million in "stolen" money.  He wanted her to do "an investigation" for him.  Uh, huh.
Well, we're broke-up now, and it turns out she's now apparently getting "lots of money" from Mr. Mystery Mastercard man.  For all I know, it was my ex-girlfriend calling me tonight from some telephone boiler room in St. Catherine's!!
If this sounds really twisted, it's because it is!!  I may be really reaching here.  
If anyone reads this message, and successfully identifies the owner of (905) 327-7829, I'd be very interested to know that name.  So would the authorities.

December 2,I got a call from (905) 327-7829, as like many of the comments i have read here, I awnsered and there was silence on the other end. I waited for a response, but eventually heard a mans voice, sounded like background noise. Curious I called back the number and got a busy signal, when tried again, no awnser ! Think i will keep calling, HOW DO YOU LIKE ME NOW !!!!

I got a call too from this number. Getting sick of these things. IF I had time and money I would to St. Catherine's and actually hunt down these people.
This is where the number is located.
Perhaps someone in St Catherine's can phone the Police. It is a attempted fraud from I see.

I got a call this morning (Monday) from (905) 327-7829, and now that I see all of this online - I'm glad I didn't answer!
