Who called from 2158251150

SCAM CALLER.  With the 2016 US President this will all be cleared up.

Att calling.  An att robocall none the less so they violated the law of scamming

its Att.  You may have a past  due bill.

ATT saying that they haven't received my old broken phone that was replaced.

it's not AT&T, It's a thief looking to steal phones by getting your information and then submitting claims using your name and plan
