Got a call at 1:20 pm eastern time on 2/13. When answered, caller hung up.

they called, but did not answer when I answered.

they called 3.6.08. and hung up.  At first I thought I'd return the call, then I thought it's long distance, why bother.  No caller ID showed up

got a call 3/25/08 @ 11:45 cst am. Caller said something bout who handles the phones service & then disconnected the call.

It was AT&T (or someone claiming to be AT&T) that wanted to switch my phone service

The first time they called it read "unknown caller" on the Caller ID.  The second time it said Bay,ATT.  It actually was AT&T.

Called at 4:28 pm, Answered and no one said anything, Caller ID. Bay,ATT.

Called at 2:15PM.  No one there.  Wouldn't be surprised if it was a sales subcontractor of AT&T like other posts here say - we can't get their sales subcontractors to stop calling us.  They used to call almost once a day - at least we're down to once a week or so now!

called 12:56 PM eastern - no one there when I answered.  Caller ID says BAY, ATT.  We recently switched from ATT, so maybe they gonna perter the dickens outta me to switch back

...taht is to say, "...maybe they're gonna pester the dickens outta me..."

Some rude Spanish speaking female called speaking in Spanish and when I repeated "Hello" she asked if I speak Spanish. I said "no, why do you want to know" and she curtly said "goodbye" and slammed the receiver down. I can see by the posts she is a mental case.

I received a call 2/14/08 at 9:14 AM on my business cell phone with this number identified.  Unfortunately, I did not get to the call quick enough and it went into voice mail.  No message was left in my voice mail.  I called the number back and heard a voice message stating that the number was for "AT&T's Win Back Division".  I did not leave a message either!

Repeated calls to my office and it immediately hangs-up
