862 824 52253 IS a prepaid AT&T calling card id

called 12/22/13 6:30pm . I was on another call when this one came in and in the process lost 1st call and got the 'unavailable' and lost it trying to get my first call back. This showed as an 11digit number without spaces. I was able to add the 'number', if that is what it is, to my reject list. Only time will tell if that is in fact the number they were calling from.

Block this number from your phone. These are the credit card (lower your interest rate) scammers. I blow a whistle into the phone to discourage them. I have begged, pleaded and yelled but they don't give up. Don't answer! They waste your time and minutes if on a cell phone.

I believe it's a dummy number.  There is a particular client that I sometimes will not answer.  I received a call from them, then immediatly afterwards this # calls and they will leave a vm.

Annoying

Do yo have some info about this number?

Got my second call within several days.      Started out . . . . If you are ___________  (it was blank) please press "0"    Automatically disconnected after a few seconds.   Tried to call back to learn who it was and message stated # was disconnected or changed.

The number, 862-824-52253 spell out 'UNAVAILABLE', which is what the caller ID sees.  In other words, you aren't seeing their number and can't get their number.  And it's highly irritating.
