Who called from 7732426105

Caller let it ring a few times, then hung up. Caller ID reads: Chicago, IL

Called Aug 24 @ 05:21 PM but left no message. Called back this morning and got the three rising tones followed by a message saying "The number you have dialed is not in service" and then a single long tone rising from low to high pitch then my call was disconnected.

I'd say this is a spam/scam caller for sure. Most likely the number is faked.

CID says "Unavailable, no message left.

They wanted to know who paid my gas bills @ my house. I told her I have an all electric home. She hung up
