S9 have been available for sale on Bitmain for a couple weeks as long as you have been willing to buy with BCH. Today they are "Out of Stock" on Bitmain site and these offers for sale suddenly appear here. Coincidence? Or Not? It sounds like a scam.

I hope its ok to post this type of question here. I do not see any customer service link on the pool site.
I have a payout transaction that is unconfirmed since yesterday, now 24 hours old. Still pending in my wallet.

Wait it out or how to escalate the issue with slush?
