Switched the family of 6 over to T-Mobile about 14 months ago. We owned all of our existing phones at the time, but I got a new iPhone 6s when we switched over. From what I was told at the time (both over the phone with TM and at the local store) I _thought_ I was going to get a recurring monthly credit of $7 offsetting a 24 month "lease" payment of $27 (plus fees that made it around $29). IIRC I also had to pay sales tax up front.
Recently I noticed the credit had gone away on my bill. The folks at the local TM couldn't tell me why, so I called TM support and they said the credit was only for 14 months. I don't remember hearing that when I signed up, but I did get a number of different stories from different folks at the time (there were a number of different promotions) and I may be misremembering.
Anyway, my current bill says that the "balance of remaining payments" on my phone is $108. I always intended to purchase my iPhone eventually, and so I asked the TM guy on the phone whether I could now, and how much it would be. He told me a number well over $200 (maybe $260?)
So what, if anything, does that "balance of remaining payments" mean?
