Sold lease / remaining balance

I’m a little out of options at this moment so I am looking for an advice on this one.

I sold a car to a dealership where the payoff shown in the contract was around 27600. And the dealership sent me today a copy of a copy for internal use of the check they sent (supposedly) to Kia and matches the amount. So the positive equity they paid me is right in this case.

But when I call Kia, they say the dealer only paid the remaining which was 27300 (I made a payment after the car was sold about 3 days later) and I have $0 balance with no refund from them.

So I have a $300 lost somewhere, Kia does not give me anything besides the payment history and the dealership sent me this crappy looking scan of a printed copy of a check.

Someone is not telling the truth and I am a little out of options.

Thanks in advance
