For the past 2 days I have received 2 calls from this number. The display reads "ATT SVC CTR" I didn't answer and they didn't leave a message. I have had ATT U-Verse for a few years. When they need to reach me they leave a message. I suspect this to be a nefarious caller. Blocking the #.

Calls periodically - I usually don't answer and a message is never left - I did answer today and just got dial tone. I do have ATT services but usually all communication is via email. I am going to block this.

This is AT&T calling about adding on additional services to your existing U-Verse account.  Answer it or not; consider it spam or not; but it is a legitimate marketing call from a company you've previously agreed can call you.  If  you want to turn it off, go into your account or call AT&T and tell them you only want to be contacted via email.

I received various calls from this number.  They said they were att, and said they were offering a lifetime rate for hbo at $9.99 price if i would just give them my passcode.  I messed w them a while since i knew they were frauds.  I asked them all about their other services and if they could lower my bill, then said i had to go and would call their 800 number to order hbo later..ha.   fraudulent callers, and att has confirmed they never ask for passcode when they call.

Caller ID:  ATT SVC CTR  Hang up after machine answered.  They keep trying to find victims in 2017.
