They keep calling you even when you press on the option to remove your number right?

I've been getting about a call/day on my Bell Mobility cell phone in Canada from a variety of numbers:
416-000-4469, 416-000-1934, 416-000-4463,416-000-44987,416-000-1357,416-000-9971,416-000-5319

It's getting really annoying even just ignoring them when they call...they invariably catch me in the car, or somewhere else where I end up making a mad scramble to get the phone - only to see it's another damn telemarketing call.
