Numerous calls from this number for several months, never any answer! Want it to stop.

I am sick and tired of this number calling our home. All I can say is STOP!

The number 613-656-2600 is showing up almost every day on our call display.  They have never called when we are home; it is rather unnerving to have the same number keep calling and never once leave a message.  When I called the number there is a message in French...I don't speak French, so don't know what it's saying.  I really wish they would stop calling!!
