Who called from 4805431392

I have gotten several calls from this number within the past few days, at least three today.  I have answered it only once and no one spoke.  The letters AGR also show on the caller ID.

Got the same call today and the weirdest thing was they just listened and then hung up.....why do they bother to call if all they are going to do is hang up on me....how rude. Hope they go away and never call my home again.....

I get calls daily from this number and they just hang up and when I call back they hang up please help

I get calls from 480-543-1392 as AGR, and they always hang up.

i get calls from this number at least a dozen times a day and no one ever responds when i answer or leaves a message if i let the answering machine get it.
