They use robo calling machines that dial numbers consecutively and if you answer it records the response and moves on to the next number. If a person answers it will immediately forward the call to an operator or record the time as "someone is home time" for a live person to call back around that specific time. If an aswering machine picks up it will just put you back in rotation for another annoying call.

Robo machines, used by debt collectors, have manually entered target numbers that are supplied by banks, credit card companies or whom ever is trying to collect money owed.

Just turn the ringer down, check the caller ID and smile if you don't recognize the callers number or name.

THEY CALLED AGAIN TODAY - THEIR CALL WAS BLOCKED.

QUIT BITCHING FOLKS - BUY A CALL BLOCKING PHONE!

YES, IT REALLY IS THAT SIMPLE!

Why

Numerous calls from this number, evenings and weekends also - no message and when you try to call back it's busy or rings out...
Has anyone else notices an increase in the amount of call like this over the past few weeks or is it just me??

I HAVE NO BUSINESS WITH YOUR COMPANY.  I AM ON THE DO NOT CALL LIST.  DO NOT CALL ME AGAIN!
