Big Mystery

I bought a brand new, carrier unlocked phone from Samsung directly and decided to sell it. I am not a TMobile customer as of now. I use Mint mobile personally only because it is cheaper for me. I decided to sell the phone to a used, online electronics store and they quoted me a ridiculously low price. They argued that it was still under the trade and program, which is understandable and that was their reason for the low price. 

If you bought straight form the manufacture, who’s Trade in Program was it supposed to be under, and did you still owe any money on this phone? Trying to wrap my head around this.
