Charge for retuned phone

For the past 6 months your team has been trying to collect $ for a warranty exchange phone that you have proof of receiving. We have spent HOURS in communication sharing tracking #s, screen shots and all sorts of detail regarding this. Your team continues to acknowledge that they received the phone and yet the amount owed is still there. The latest response is that they need to make sure they didn't receive an empty box. You received the phone in November. If there was an issue then it should have been identified then. There was no issue btw. The phone was in the box. I am now getting notices that my phone will be turned off unless I pay the nearly $900 payment for a phone that you have proof of receiving. Can't go to another phone carrier without having to pay the balance in full for the phone I have (which is only deeply discounted if I stay monthly). Fix it.

We have been more than patient and accommodating.
