DEALER WAS GIVEN A PROCEEDS CHECK BY THIS BANK WHICH INADVERTENTLY INCLUDED THE PAYOFF FOR A TRADE-IN AUTO. THE DEALER IMMEDIATELY CASHED THE CHECK. WHEN CONTACTED, HE SAID HE NEW IT WAS FOR THE WRONG AMOUNT AND WOULD RETURN IT. HE WAS CONTACTED AND HE SAID HE MAILED A CHECK FOR THE OVERPAYMENT. THE BANK HAS NOT RECEIVED THE MONEY, AND ANY ATTEMPT TO CONTACT THE DEALER NOW GO UNANSWERED.
