Caller ID states its "officially" Att. It went to answering machine and caller hung up. When I called back, you can hear the call being forwarded. A male answers with "hello" and does not formally nor professionally present himself. When asked who he was and what he wanted, he says hes not informing me of anything since my call is blocked. I said, well, it matters not if my call is blocked, what did you want. He says...what number is this. I said, it matters not, would your reason for calling have changed? He says, well, I mustve misdialed. Right.... I predict its a scammer that is faking the caller ID. Beware! Att representatives are more professional than this....at least I hope so!
