Smart Pay Lease Lost device, but they will not let me pay fair market value or end lease payments Internet

 I was misled into believing that I was signing up for a lease to own after 1 year plan. After 1 year of owning this device, I threw it away because it was outdated assuming I was about to pay it off. I was wrong, I got a message a few months later saying I owed hundreds of dollars and my account was about to go to collections. The payments kept coming even after the one year. I tried contacting the company. I called multiple times and nobody in customer service had any idea what I was telling g them or what to do. Finally someone told me to email a letter explaining the situation and they would tell me what to do. At one point they said I have to file a police report for a lost device. I'm still stuck making payments and have paid for the device many times over. This is the worst company I've ever dealt with and it has taken up far too large a part of my life.
