iPhone 6 paid off and still showing financing on my account
Hi, I paid off a the iPhone 6 on my account awhile ago and recently upgrade to an iPhone 8. I was selling the iPhone 6 to Gazelle and they said it was still being financed on my Sprint account and wouldn't accept it. I have a family account with four devices on it. The last time I paid toward the financing of an iPhone 6 was December 2017. How can it any of the old devices on my account still be listed as financing 6 months later?
