From one of my multiple chats with TMobile:
Essentially this: I was a Sprint customer. After transition to TMobile, my wife and I upgraded our 13 pro Mac phones to 14s with TMobile. We were told multiple times via chat and in person at store that we would no longer be paying on the 13s once traded in. You can even check these chat logs for guarantees that we will no longer pay for these phones. You guys now own the 13s. We will not be paying on these phones as we no longer own them: you do. If this can’t be resolved today (as this is my 5th time attempting to resolve this), we’re looking to turn these phones in, leave TMobile, and contact the BBB. I don’t mean to be rude, but I do mean to be direct.
update: last rep said that employees had lied to me and that I had no choice but to pay a lease on devices owned by TMobile. Is this a legal issue at this point?
