They called me every two hours today, 4:30, 6:09 and now at 9:05 p.m. Eastern Standard time, I'm getting really pissed off here, I tried calling back but it won't let me, they never leave a message either.
I used to be a telemarketer. Go through the wait and inform them to remove you from all their contact lists and that you are interested in nothing they have. When you do, wait for an affirmative answer to this. The moment you get one, hang up. If they call further, you can legally report them for harassment.
