They call almost everyday, listen and then hang up.

Number called today around 10:00. Claims they are with AT&T and wanted to 'review' the bill to see if they can save us some money. Told her I don't HAVE At&t... she was like... hmmm weird cause I am looking at your bill.....I was like 'What bill.. we don't HAVE at&t". Then said something about seeing an adress of our other office. Told her to "call that office then".

Tried calling back the number afterwards, and gives me a message:  "we're sorry, you've reached a number that is disconnected or no longer in service".

So I suspect it is another one of those companies claiming to be AT&T.

For 3 days in a row this number is showing up on my business caller ID and reports the number is from Michigan

Ask for the decision maker

Keeps calling-I don't answer and you can't call the number back.

This number has been calling our office line for days and days and no one is ever there. Very annoying.

this is the second day in a row @ 4:15 is that this number called but no one was there.

As soon as you answer the phone they hang up.
