JT just give Vermont his money back.
I would feel just like Vermont and would be using this forum, as a tool, to resolve the issue as others have in the past. There are countless entries in this and other forums of unhappy customers needing what seems to be a simple solution. What will it hurt? Refund his money in full. Then sell the machine to the next customer. No skin off your nose.
I was once told that every upset customer will run off ten. If this holds water, you just lost 10 sales trying to hold on to this one.
Have a great day,
