Like you, I keep getting calls from these idiots, ON MY CELL PHONE, which costs me minutes, of course. I would like to threaten them with a lawsuit or invoice (at $50 per second) to see if they'd lay off. Asking them to, nicely, doesn't seem to work. Maybe I'll get cousin Guido to take a few of his boys over and have a little discussion with them!
Calls every day between 10 AM and 2 PM. They want me to renew a magazine. I've given up on trying to stop them as they ignore my efforts. I finally just pick up and hang up.
