I'm having a somewhat similar to above but a bit different problem.
So made an order of a few S9's. Then sent part of the BCC amount from coinbase account. Then, while i was exchanging the rest to BCC in my other wallet, the order expired (they seem to have changed it from one hour to 30 min).
So now i have almost $2k stuck in a forever expired order.
Has this happened to anyone??? Plz advise.

Opened a ticket, but looking for advise/similar issues from others..
If you contact support ASAP you might be able to pay the difference right now. I would wait to hear what they say, rather then keep paying.
30 minuets to pay for an order is impossible sometimes. I paid for mine in the first block after I placed the order and it was at 30 minutes.
