They just started a service to register your number as one to which telemarketers can't call. Not sure how well it's working so far...
They did have that zapper unit for a while but that's not really a solution.
But somewhere along the line, when did it become OK to call during family dinner? Early on Saturday morning.
Or there's a new tactic. They call and ask you in a very friendly, excited voice by your first name and when you say "this is he" because they don't sound like traditional telemarketersthen they tell you who they are. That's a bit foward.
They're a plague.
