They're probably "random dialing."  They should have "no-call" lists, but if they are doing random dialing, they either don't have or don't pay attention to the do-not call list.

lol - Canada is not a cave...they will not charge you $500 a minute....lmao funny though

Person from 647-258-5690 called me for duct cleaning services. Don't we have a DO NOT CALL LIST?Caller ID: Unknown nameCaller: Duct CleaningCall Type: Survey

Anna the mover calls. Call 647 477 8099 and remove your number from the list

This is the number on a letter that came with a check for $4500.00 telling me I won $100,000.00. I was to call this Canadian number, and give information before I deposit the check. THIS IS A SCAM!!!! Be careful, the US Banks won't let it be deposited unless there are funds to cover the check in your own account. When I spoke with Bank of America, they said what happens is the check bounces, and Bank of America holds your account to pay for the bounced check...and then the scam artists have all your account information from the back of the bounced check. BE AWARE!!!

this number keeps calling my line at work ... yesterday and today , but i'v emissed the calls and there hasn't been a voicemail ...
