I'm in the same situation. ACCOUNT_DISABLED, which only appears in the Buying/Selling popup.
Waiting for 1.5 day now. Only had the same automatic e-mail from them as already mentioned in this thread.

I have an old account from 2013/2014, ofcourse with 2FA enabled (almost from day 1). Back then there was no AML/KYC. Now it is. I have nothing to hide, so I upgraded my account to Basic and then Enhanced on 08/02 (4 days ago). Never seen a single message about a disabled account.

When BCC came available I transferred it to Bittrex without any problem.
Waited 24 hours for the 20 confirmations, clicked on the SELL-button within the popup, and there it was: ACCOUNT_DISABLED.

Opened a ticket, but no reaction yet. That it's sunday right now is irrelevant: They earn hundreds of thousands of $$, launched BCC just before the weekend. And then they are going to celebrate the weekend??

I've also asked for delay damages, cause when I wanted to sell the BCC price was way higher than now. Furthermore, If I knew that my account was disabled I could do something about it. But with zero on all balances, waiting for 20 confirmations and seriously NOWHERE a message that my account was disabled, I couldn't have known.
And not to mentioned that I have succesfully done the AML/KYC just 4 days ago...

Today I tried to withdraw my BCC, and guess what: ACCOUNT_DISABLED.
So you can succesfull deposit and than your funds are locked...
