IF YOU EVER WANT TO KNOW WHO CALLED YOU and REMAIN ANONYMOUS, DO THIS;
PRESS *67 and wait 3 seconds for the beeping sound to stop, and then dial back their phone number.
Doing this displays 'PRIVATE' on their ID Caller display -- they cannot see your number. Chances are you'll get a recorded message OR a message that says it's not a working number. Don't leave a message.
Next time these pricks call tell them to STOP CALLING and to take you off of their call list immediately ... and then hang up. Don't let them suck you into a crazy sales pitch or conversation.
If they call back anyway (and they probably will) then it's time to;
BLOW A REAL LOUD WHISTLE INTO THE PHONE WHEN THEY COME ON THE LINE. Works every time.
I did this this to them a few weeks ago and they haven't called back.
