877-737-3999

Advance call center tech. On behalf of AT&T. Call the number and put yourself on the Do Not Call List.

I get this phone call. And I call back and no such number. 877-737-3999

I keep getting calls from this number.  I ignore it and no message left (of course not)

they call all hours of the day and night very bothersome

1-877-737-3999 calls every day no one there

Today, June, 9th I've got16 phone calls from UNKNOWN number  plus 5 calls from # 18777373999. "They never answermy calls. There is just a noice. Any explanations?

Yup, this makes every day for the last 2 weeks or so.
Let go to vm. No message left

They have called yet again. They haven't missed one work day in a week or two. one call a day.

repeated calls daily. no id and will not leave message. I will not answer any of theses calls

these people call everyday, they talk over the top of you, They are calling from AT&T phone company.

They have auto dial,if you stay on the line a littlr longer,someone will start talking.

I get this call several times a week, no answer, no msg on vm.
we're registered on the 'do not call list' however, if they are AT&T (who were are previous carrier) then they fall under the right to call us, unfortunately. Using Ooma, going to see if I can filter this number out.

When I answered the phone, there was a recoding telling me they were still trying to connect my call and to please wait for this important message.  The recording was repeated 6-7 times, then the call was disconnected.  I called the number back and got a recording telling me that I had been contacted by Advanced Call Center on behalf of AT&T to let me know of some special deals they had. I could leave a message with my name and phone # if I want to be out on their do not call list.

Caller hangs up when answering machine turns on.

Poor state of a company.  Shafty to have to call people to drum up business.

The number was 1-877-737-3999...they did not leave a message and when I called it, it said thank you for calling customer service press 1 for english 2 for spanish...did not identify who it was.

That's what happened to me. Very odd. I do not believe ATT uses third parties to sell stuff legitimately.

They call each and every day (Weekends included). Never answer because they always seem to know when we are not near the phone. Never leave a message... Their Loss

This really works! I just tried it. I am glad to know about the "do not call list" THNAKS

I receive at least 10 calls a day starting at 9 a.m. (Ohio time) with either Incoming Call or an 800 number.  I have finally started accepting the call (no one on the line) & hang up immediately.  Sometimes after this I will get 3 right in a row or none for a couple of hours.
