I received a call from this number and when I told them I didn't take calls from telemarketers and they hung up.

I am on a do Not call List, which I thought was legal in this province,.  Why do I still get these multiple calls from this annoying Duct Cleaning  at 647 558 5728 ?

Same old story. Unknown number calls + I don't pick up + they don't leave a message = what they have to say must not be very important.  And yes to the previous comment, telemarketing is not allowed in the province of Ontario if you are on a 'do not call list'.  The problem is, the country that these people are calling from could care less about our laws and our provincial government is not far behind i.e. they don't really care either.  Cheers...

got call. i picked but kept silent as i felt this number is not known to me. after few seconds i heard recorded voice as "good bye" and other side hung up than.
