I recieved a call from this number but did not answer the phone. Then searched the number to figure out who it was. Thanks god I did not answer. Above website is where you should be reporting this so the police can warn and investigate.

Adding to Message from 'cw' - These calls from (905) 595-8640 (Brampton, Ontario, Canada) and (905) 346-4828 (St. Catharines-Thorold, Ontario, Canada) - both Unpublished Landlines.NOTE:  They have been calling weekly for past six months or so; started at least during summer of 2009...Last call on Saturday, February 27, 2010.  Other calls from 1.+1 800-375-5872 (again, unable to locate on Internet--unpublished).ALSO NOTE:  These callers are very insistent, persistent and difficult to get off the phone. They pretend they know you but ask for your Card # (or at least the 'last 3 digits'); likewise, they try to get your Social Insurance Number in the same manner, and ask for your birthdate.URGENT WARNING:  BE VERY CAUTIOUS--NEVER GIVE OUT ANY PERSONAL INFORMATION OVER THE TELEPHONE.  ANOTHER CAUTION--DO NOT give personal information Over the INTERNET either.  If a caller claims to be from a Bank or a Credit Card company, hang up and call your own branch to verify if your bank is soliciting this type of business (such as protecting your credit card interest rates, or reduce them).TWO YEARS AGO, I had a caller (about 9:30 P.M.) call me (supposedly from the Scotiabank)...I traced the number at that time to a Scotiabank Building, in Toronto, Ontario, Canada (BUT the Scotiabank NO LONGER used that building for any type of branch or credit card business...so, the building ONLY HAD THE NAME OF THE  Scotiabank on that building.  THESE PEOPLE ARE VERY INTELLIGENT AND CREATIVE in the way they are trying to scam people.AGAIN, BE AWARE...If anyone asks for any personal information about you, BE SURE TO HANG UP...STOP THE CALL IMMEDIATELY...give no information to them.  DO NOT BE Duped.  Protect your identity BECAUSE NO ONE ELSE will.  May you all receive discernment in this area.  ALL THE BEST.

It's been a while since they called in, still the same Indian person. Strangely he offers to reduce rates for Visa and Mastercards credit cards.

They called me over 6 months ago and said they could get me a better deal on my credit cards. I told them that I am on disability and have no credit cards, which is the truth. They did not call back until Feb. 25 2010. They did not leave a message.If they are calling you frequently maybe consider telling them that you are on disability and have no credit cards. A lie? Yes, but I would not have a problem lying to these waste of skin scum bags.If anyone can come up with an address please post it. So far the best I can do is somewhere in Brampton.Coex Dave

it number is a scam

Ok... these guys are scammers!!! Big Time!!!
First they told me that they were Mastercard and that they were going to lower my interest rate to 6% for being a good customer. Then they asked me for my address (which I told them they already had because I just got my new Mastercard), then they asked me for my expiration date (which I told them they had), then to read out my credit card number to them.... WTF!?  By then, I knew it was something like a SCAM because when I hung up and looked up their number on the yellowpages.ca... I saw all of these posts. BE CAREFUL PEEPS...
Since I had hung up on them to investigate they called me back twice... while I was talking to a REAL rep from Mastercard.
oh ya, by the way the guy's name was Alex Johnson and his title was Credit Card Advocate and that I could also reach him at (403) 648-9228.
