Have the same answer. I've red C-CEX documentation, and there isn't written nothing about the duty to wait for the announcement. C_CEX let us generate the SSV address, and we sent there our money. I want my money back. If they lost them, they have to buy SSV from the market.

C-CEX deposit rules:

"Cryptocurrency deposit and withdrawal rules
All cryptocurrencies are deposited by sending the amount to the Exchange's generated users address. These addresses are generated on demand by clicking "New address" in the "Funds" section.

Cryptocurrency withdrawals are made at the "Withdrawal" interface in the "Funds" section by sending available amount to desired address.

All cryptocurrency deposits and withdrawals are automatic and initiated instantly. All possible delays with transfering funds after successful withdrawal are not related to Exchange. Successful withdrawals are always confirmed by transaction ID.

We are not responsible for deposits and withdrawals made in wrong forks of specific coin's blockchains if there is no updated wallet version in official coin site and no notification made by coin developer."
