unless they call you on a landline - all you need is a call blocker app- if you have an Android there are many free ones and if you have an Iphone 4s or later you have o on your phone already- I have these guys under at least four numbers on my phone. they like to change it up

Yep keeps that [***] rock in! Lmao

i do not answer any call from a number i do not recognize.   but i do come here to try and see where the call came from.
my advice,  don't answer your phone unless you know who it is

I do the same thing, I don't answer and have a number blocker but these calls still come through with one ring before they are stopped.  They call me at least every other day.  SO ANNOYING!

I was told that they can't be removed from the call list because of them being in Canada.
