This number calls you and when you answer they hang up but when you try to call them back you get a message saying we are sorry we was unable to recognize your response and then it disconnects

Windstream Communications, call when your phone bill is past due.

This number called both my cel and home numbers and when i picked up hung up without responding to me at all.

It is a customer support line from Windstream. Normally not a problem. If you get a call from them you can call their main number 1-800-325-9415.
Ask the rep to track down the call to your phone. They keep a log of their outgoing calls. Sometimes their "payment reminder" service just doesn't work right. But their reps are usually helpful if you ask.

They called me..not knowing my name, just my phone # and claimed that I had a bill of over $600.  Asked me for a payment.  I don't have service with windstream and never have ?????  I am going to look into this one.  Is this a scam???  I told her I did not have service with them she said "oh you don't" and hung up.
