Anyone else been having issues with BitcoinFog?

Made a withdraw request around 8AM.  About 6 hours later, it was marked as "Finished".  It's 8PM now, 12 hours have elapsed since I made the initial withdraw request, and not a trace of bitcoin has hit my wallet on the blockchain.  Tried contacting support and no response.  Steadily watching the price of BTC drop as bitcoinfog holds my funds...

Edit: Nevermind, it finally showed up.

So almost 12+ hours now, bitcoinfog marked my withdraw as "Finished" about 6 hours ago, 6 hours before that I actually initiated the withdraw.  So far no transactions on blockchain to my wallet, no response from BCF support...

It is my understanding that you need very powerful machines to mine bitcoins - sometimes costing you more in electricity to mine the coins then the coins you get in return.  Why would this at all be profitable?  Maybe I'm missing something.
