Same problem. One (approximately 5btc) withdrawal shows as processed but nothing on the chain or in my wallet . . . the withdrawal was enacted two days ago . . . and about 5 hours ago changed from 'in queue' to appearing like it has been processed (but again, nothing). Hoping it shows . . .
Mine was for over 10 Bitcoin. I'm sorry for you. I hope for all three of us that our Bitcoin show up. I am emailing someone asking for advice. Will share it if anything fruitful occurs.
