Submit final version bill to att.
I had an in home visit from an AT&T agent because I was getting WiFi. He added a mobile plan and gave me a new phone with a trade in, but I told him I still owed money on the phone from Verizon. He told me no problem and AT&T will buy the phone from them. Now I got a bill from Verizon for the phone and don’t know how to submit it to AT&T or if I was lied to and now owe an insane amount of money.
