Ok, so got an ODD question. I canceled my AT&T today and went to T-Mobile, Ported my number and everything. So I logged into AT&T and noticed my balance was 0.00, but according to my last bill I still had a Next Balance from the iPhone 6 (I upgraded to the 6S when it was launched). So I started up a chat with a rep and he confirmed with me that there is a 0.00 balance and everything is paid and clear. So i confirmed again that I will not owe anything now or in the future, and he confirmed yes. So needless to say I emailed the transcript to myself. I didn't quiet believe him so I started another chat and that rep said the EXACT same thing, this time I asked for him to type his employee number in the chat so I have a record of it. So my question is if AT&T comes back and says I owe a balance, can I present those chats as proof I was told twice, that my account is paid, cleared, 0.00 owed nothing now or in the future? Of course I'd go into the store with this information and a print out of my current AT&T logon screen showing a 0.00 balance.
