they hung up on me.

Same guy, what a joke!  I called it back too and it's disconnected!

The caller absolutely had an Indian accent, he said he needed to verify my AT&T information and that he worked for then, then he got mad when I told him that I didn't want to give him my information, he then said he already had it and was verifying.  He was very mad when I wanted to hang up on him, he actually was a bit scarey.  I Think it's a scam.  He said he had to "call me back," when I asked why he said he had another call, but funny thing is he called me to verify AT&T information why would he need to call me back? Absolutely a scam.

Same here, but he hung up when I questioned him about the call's purpose.  I immediately called the # back and it appeared to be disconnected.

Same thing here.  Calls saying they are AT&T.  Want to verify info and then pass to a manager.  Strong Indian accent.  Got an "employee number" from the "manager" S172358130.  Said I would have to speak with his manager.  He said call was from CA.  area code is PA.  I can waste these guys' time as well as anyone, but why bother.  There is some sort of rip-off or scam behind this.  I can smell it.

Calls our business several times claiming they need to speak with associate and the call is confidential. We've told them to remove our business number and they still keep calling.
Googled the number and discovered it's a restaurant in Philadelphia, though I doubt a restaurant would need to call us several times. Something strange going on with this number
