No, we are not. By FTC's mail order rule, you're only granted a refund if the company fails to ship within the stated timeframe.
KnC says they'll deliver within September. So we're only allowed a refund if we haven't got any machines by october.
And any other regulation would be completely stupid. What company would start production based an pre-order money if they have to be afraid that people can just pull out whenever they want?

And aside from that, the FTC has zero say in this, since KnC isn't located in the U.S.
