After dealing with KNCminer, I've come to the conclusion they are a very unscrupulous bunch.
I've been attempting to get a refund from them for a product and they use every trick in the book to not refund any money.
They claim it takes 3 to 10 days to process a refund. In practice what happens, is they wait 10 days then look for some additional info they need from you, claiming they cant send the wire, then they wait another 10 days after you give them what they want, then look for more info they need from you. I suspect they keep this up until its "too late" to refund anything.
