Male comes on the line and (politely) asks to speak with the person who is over the AT&T phone account. We get these calls fairly frequently. Obviously not AT&T, and do not confirm anything with them by saying "yes" otherwise you might see some unexpected surcharges sneak up on your next AT&T bill. It has happened before. I politely let him know that "We are all set with our AT&T services, but thank you" and promptly hang up.
Have received several calls from this number at our business using assumptive selling tactics to switch AT&T service. Have advised on numerous occasions that we are all set. This time the lady was cursing as she was speaking with someone else on her end, then hung up when realized I was on the line.
Got a call from a somewhat polite sounding man asking if he could speak to the person that handles the (it sounded like Century account) I asked the WHAT account & he hung up!
