I owe money to Bell Canada, and they keep calling using different numbers just to reach me.. I haven't called back and I never answer, they [***] so many times my account, they'll wait ;PP
I have done the same thing, filed a complaint to the CRTC, for over a year I keep telling them I am not interested in your service and they keep calling me, every month, sometimes twice a month. And the worse part is they call at all hours, sometimes early morning waking people up or late at night. Someone has to put a stop to this.
