As of Dec 21 I had 0 balance . My new bill ftom dec 22 to jan 21 ..is 785.00 added onto my regular phone bill . They said on customer service and one chat rep it was a past due balance. How can it be past due balance if dec 21 I had zero balance. And dec 22 bill started out as 0. And my bill also says it was for a device buyout charge. I did not do a device buy out or authorize it. I have always done mine with a 2 year contract. My phone they have that associated will has been paid off for over a year. They are both answers I got are incorrect!! I've talked n talked to them and still say I' owe the 785.00 that was added to my regular bill.
