Just received a call from these guys too.  I didn't say "hello" since the number was unknown to me and waited for a response.  I could hear a male voice talking in the background as well as other unintelligible chatter.  Since I didn't receive any response, I simply hung up.  End of story!

Just got a call from them too. The guy on the other end could barely speak English and was saying something about a visa card. Stupid call had to get me out of bed ;(

got a call an hour ago. missed it. looked in directory - said the number is unpublished and located in st. catharine, on. they did not leave a message. what the bustards!just look up at the number sequence: (905) 345-6789!!!!!

Got two calls in one day from this number. I never answered. Don't know anyone from the 905 exchange.

dont answer the phone!  I talked to the guy, figured it was some credit card scam, which it was, he wanted me to verify my name, my bank, my credit card.  obviously i'm not stupid so i just made up some stuff that wasnt real, but after i didnt feel like talking anymore and hung up, they must have thought they had a good chance of convincing me to give them my real info, because they called back 20 times in the next 10 minutes.  finally i talked to him again, but he eventually figured out i was just leading him on and he hung up on me.  first call received 9:13 pm, last call received 9:23 pm
