The Do Not Call list hasn't stopped these shmucks from calling. Now when they call I answer and just keep punching buttons until they hang up. It seems to mess with the robo dialer and I can usually go a week or so before I get another call.
They called and hung up. I called back from my work phone and they answered in Spanish. I kept hitting the keys and the lady (in Spanish) said, "How beautiful". I kept going on and on and she was ruthless, she started laughing. I kept going. I had to stop when a call came in at work. I thought it was them so I hung up and my boss answered. It was not them. I really wanted to see how long this person would wait while I rung rung the keys. Maybe next time.
