I have 300,000 EUR blocked in "Bank Transfer Completed" and "SEPA Bank Transfer" with no updates for 2 weeks and no money in my bank account.
Their support is saying they are working around the clock and it will take extra time but does not say how much.
At this point I don't think I will ever be receiving this kind of money from cex.io and I am thinking to talk to a proper legal firm that can start a legal action.
My guess is they don't have enough cash to process all withdrawals and are waiting to cash in from ETH and BTC sales.
