They call me everyday at ~10 AM. Usually silence at the other end.

These f-ckers keep calling my line too.  They need to executed

I did the same as "proactive". The company recording identified itself as:Canadian Premier Life & Legacy General Insurance.I phoned the # back and after asking for English/French selection, the automated menu asked if I wanted to add my phone number to the "Do not call" list to select menu option #1 and after confirming the phone number I typed in, it told me it would take up to 30 days to remove my number from the call list.

Called claiming they were from CIBC and then tried to get private information from me.  I said I didn't feel comfortable giving out any information to a random caller claiming to be my bank and ended the phonecall.  They still call frequently, though, never leaving messages.  They are bastards.

Never leaves a message called me 4 times in the last week

Called several times and didn't leave message. So annoying.
