Hello, I have had the same issue with only a little amount of bigger transactions coming through. I got worried and tought I was scammed, but after waiting a couple of hours after the "FINISHED" state at the BitcoinFog site, I had all the money in my wallet, that I was sending from the beginning.
So I think they're NOT scamming. More probably having problems with delays in their services, as stated on their website a couple days ago.
If you're still having the problem; just wait. Don't panic or anything. Im sure you will get the money soon. You shouldn't have to wait for days, but a couple of hours extra I think.
(Sorry for not the best english ).
