I called this number found on one of the earlier posts:  310-251-5420 and got a live operator for callerID4U.  Just thinking that a reverse form of constant callbacks to this number possibly with your complaints or instant hangups might be as annoying to them as it is to us

I put my land line on my AT&T bill for $10 a month and never answer it. I bought a cheap cordless phone and keep it in my desk drawer and check it weekly, sometimes.

Best $10.00 I have ever spent. This way they can call and no one will ever answer and I HAVE turned the ringer off so I can't hear it.

SO CALL AWAY SUCKERS!! NO ONE CAN HEAR YOU.

Called this afternoon.  Caller ID shows "RDS Service".  No message left.
