I get numerous calls from 800 registery co..  always a different number.. no one on the line..  and cannot call the number back

This is from a malicious caller, who will run up your toll free bill relentlessly. They call from a different number each time, to prevent your phone company from blocking them. They hang up as soon as you answer and do not pick up if you call back. This last call came at night, waking me from a sound sleep. AT&T's subsidiary Southwest Bell appears to be providing phone service to these people, although it has been repeatedly told what they are doing and asked to cancel the account. All this conduct appears violate federal law. The FCC has opened a case, but will not take action until more victims complain. You can file a complaint through their web site. Refer to their Case # 11-T00802695-1. It also helps to ask your congressional representatives to follow up with the FCC,

Some weird stuff.  All the 956 calls I get are like this, no one there, no message, nonstop rings if you call back.

Someone is giving me a miss call on my number

Please stop calling my number and then hanging up.

nothing

This number calls me several times a week. There is never anyone there when I answer and they do not leave message if I don't answer.....Uggggh!

I get calls from this # in the middle of the night. Caller ID says 800 Registry Co.
I called the number back but it just kept ringing.
