They are a scam - they pretend to be AT&T/Phone company and try to trick you into switching long distance carries.  Tell them to F*#@ Off and hang up...

This is an automated dialer.  I called back.  I waited for her system to dial out since you does not know how to use your equipment.  I heard it dial a number.  I said hello.  She picked up.  I ask who is this.

"This is Mary with at&t."

What do you want ?

"Hi, this is Mary with at&t.  I am calling to sell you lines and internet."

This lady is NOT at&t.

That is a lie.

She probably is trying to sell lines and internet.  She probably is a rep for at&t.  She cannot, however, make herself out to be at&t.

This company is some kind of solicitation.  I can't understand how they keep calling when my number is on the "do not call" list.

No message.  Caller ID says 'Universal'.  recieved calls from them before.
