These people keep calling, leave no message, and only have a brief phonemail message when you call them back, which they never return. May their mothers rot from syphillis.

They just called me.  They buy telephone lists from other companies and then try to sucker you into something.  I know this, because I am on the Canadaian Do NOT CALL list.  They could only have gotten my telephone number from another company profittering off the information, I gave them so I could get the information which I wanted or needed.  This selling of names and telephone number has to stop so the sane persons on this planet can get some peace.  519 is an Ontario telephone exchange.  I live in Saskatchewan and other than being Canadian, we have nothing in common and there is no need to contact me unless you are doing so personally to be my friend or to "give" (no strings attached) me something wonderful, that I will need.

got a call from them this morning, but didn't answer. I used to get calls from a 514 #

Same here, they just started calling last week from 2 different numbers.  No idea.  When I try to call them, they disconnect.

I have been receiving calls on my cell phone from this number, i never answer it but they have called twice a week for the past 2 week. I called the number back but said the voicemail box was full. It is so annoying.
