We have been receiving calls from this same number for a week now -- multiple times a day. Just this morning when it happened and I answered there was a recording saying that "Mike" from the carpet cleaning service was offering a deal -- I pressed 1 (per the instructions) hoping that would connect me with a live person but it didn't. Then the call disconnected. AT&T tells me that they cannot identify the number. It was disconnected over 4 years ago with them.
