Will I be eligible for an upgrade?

So I purchased my iPhone 5s with a new contract and everything on my dad's plan in May of 2014, and I checked with ATT and it says I'm eligible for a upgrade if I trade in my device or pay the installment fee. I'm wondering if I trade in my iPhone 5s which has scratches and bents, but it fully works, will I be able to get an iPhone 6s?

No they never give you an upgrade unless you pay for it
