First what was the terms of the first lease? What was the payment? How many months left? When you leased the used Toshiba did you check new or used on the lease?
Fisher is right take care of the customer and they will take care of you. Yo need to build that trust and respect back up because right now the customer thinks he got a lemon and you do not care. If he believes that you need to act fast otherwise he will shop you and that will be the end of that customer. Honesty is always the best policy because there are too many crooks in this business. Do not try to roll them and do not sell at list you would never get the deal.....it is rare that anything is sold at MSRP.
