Similar issue here.
 
I specifically sent them the documents prior to transmitting the money .. to which they confirmed the next day "you can send".

Then it took them the full 7 days to actually credit my account, but now I sit with in excess of 41000 minutes hold.. more than 28 days left!

No response to my repeated requests for explanation or what I need to do to resolve whatever the problem is.

And they've not put a hold on just the USD. It is ALL coins. So even though I have other coin currency deposits or trades, which I have been making for weeks now without issue, NOTHING can be withdrawn all of a sudden.

VERY FRUSTRATING.
