I honestly don't know what to think. I'm more disappointed in their response to the situation than to the situation itself.
I can't change keyboards right now, even if I wanted to. But when it comes time later this year, Yamaha will be last on my list of companies with which to spend my money.
They could easily salvage this whole affair by confessing that they screwed up and dealing with it in an open and honest manner.
