I keep getting two calls a day also from (905) 247-0308 - and there is never any message, but they obviously wait until they get my answering service.  What the hell - this has been going on for weeks now!

Me too!  Everyday, at least twice, even in the evening!

This phone number shows up on my call display as calling at least twice a day and never leaving a message - it's getting very annoying!

this number keeps showing up on my call display, as often as twice a day in the last week.  Stop calling.  I will never pick up.
