Sprint sprint tells 13 year customer we won't help you Nationwide

I have been a customer with sprint since may 2001 and not had a problem until now. Me and my wife went from the galaxy note 3 to the nexus 6 our original intent was to get the note 4 but we were talked into the nexus. The phone started not getting phone calls while in WiFi. Then my voicemail completely vanished. If you called my phone you would get a carrier error message. These issues started on day 14 with the phone and I couldn't get to the sprint store where we got the phones to exchange them. I called sprint that night they wanted me to pay a 35 restocking fee for each phone which I felt I shouldn't have to pay. So I went to the store next day to get this done. They refused because I was over the 14 days I again called sprint and the rep who answered the phone gave me the run around for over an hour. I called the next day again to see if they would send us the note 4 and we just pay the difference after 2 more hours I finally got the girl to have this happen but we couldn't pay the difference until we got paid a few days later she gave me her operator number and assured me she would call me at 3pm that day. By 6:30 I hadn't gotten the call so I called. On hold for another 45 and was told that only that operator could complete that so I was hustled off the phone again and quiet angry this time. Around 8 pm I called back and demanded to speak to her by name and operator number. And I was shuffled to someone else then again to someone 2 hours layer I finally got them to send a mailer so we could send the nexus phones back and we would have wait to they were received before they would send us the note 4 which they said would be 7 to 14 days and there would be no service credits given because of the extent of service they were offering. I then stated I was recording the conversation the rep quickly hung. The next morning I called back to the same department. And was told I am beat there is nothing more they do for me after being a loyal customer for almost 14 years I'm done with sprint already called T-Mobile and should receive our new iPhone 6 plus in a couple days ...DO NOT GET SERVICE FROM SPRINT  WOrst EXPERIENCE ever
