UPS never received my package. T-Mobile reps are clueless. They are speculating that they were promised the phone by Apple, so they printed out a label, but Apple ended up not fulfilling the order so they put it on backorder. They don't show a record of a label and I don't blame the reps as they don't have all the information.
This is my 9th year with T-Mobile, and I have stuck with them through everything, including the years that they had a non-existent CS department. I've had things added to my account from T-Mobile stores that I have never been to, and been double-charged on text plans before. At this point, I don't care about the plans for an "UnCarrier". The level of incompetence shown by varying levels of customer service throughout this process has been absurd.
The grass is not always greener with another phone carrier, but it will be new. A fresh start seems likely for me. If I do receive the phone, it will be returned. My Note 2 works just fine right now.
