Received a call with the same story, that they were upgrading the internet service to fiber optic lines.  After I hung up the phone with them, I immediately called ATT directly to ask of their promotions.  They said that they would never call a customer out of the blue, unless the customer requests to be called by ATT.

Being an ATT customer I answered the call. The woman wanted to give me HBO and Cinemax FREE for three months. When I told her I had no interest in those channels and did not want them at any time. She argued with me that I could get it free and cancel at any time. I told her if that was the case I cancel NOW. Argument continued and I said NO and terminated the call.

Tried calling back since I actually was waiting for service from AT&T.
No one ever answers it just goes to voicemail even though the office was supposed to be open from 12-8. Thanks to all who post on these phone numbers it really does help to understand which numbers are scams.

This numbers call my land line 3 to 4 times a day

I have reported this number several times. No message.
