I get calls from this number to my office phone that has an extension. I don't know how they came to know my phone number with extension. I always pick up the receiver but nobody speaks from the other end; and hangs up after a few seconds.

Ottawa, rogers wireless

Called and asked for me by name; I said person not available; they said they were from Rogers but wouldn't leave a message for "me" and they could not be called backed. Telemarketer for sure.  Actually from Rogers? Who knows.

called today and yesterday, nobody there. Both times at around 11:45am.

Please do NOT call the number mentioned above -- (613) 567-0231 -- to try to stop calls from (613) 567-3619.  The one phone number has nothing to do with the other.  It is someone's personal phone number and apparently was listed maliciously in the above posting.

I've only been in Canada for two days, gave my cell phone number to only two companies... hotel (Best Western) and car rental company (Enterprise).  Would one of them have sold the number to a marketing agency so quickly?

got called by this number at 15:37, called back and there were no answers.
