Hi All. I sold a "like new" Yamaha (psr s970) on Ebay and it was delivered today. The buyer requested a refund saying "keys not in good condition" and sent pics, only problem pics are NOT of the board I sent, pics buyer sent are of a well used (psr s975)??? Don't know yet what this guy is up to but notified Ebay and we'll see what happens. I'm sure I'll have to give a refund in the end but I want to be sure I get MY KEYBOARD BACK and not the piece of junk he sent pics of.
