I was deposit BTC buy 100 BCD then after 10 minutes I received email from them that I was requested payeer withdrawal even if I'm not! Another 10 minutes later, I was attempted to log in on my account then suddenly 2FA code pop-up. The only security I was added to my account was my email. Until now I can't access my account. I created many tickets regarding my concerns but no email received from them.
Do not invest your money at c-cex.com it's a SCAM!
Sounds like it was a phishing attempt, did you go to the correct site? Did you type it in or find a link? Was it googled? Did you 100% type the right address (check the URL in your browser history)
This exchange has been stealing people's money for a long time. Their Twitter account and chat room are filled with complaints about accounts with empty balances, unauthorised transactions, vanished deposits, restricted withdrawals, you name it. They have stolen 2.14BTC (worth $8,200 at the time) from me in 2017, turned my support messages to theirs, spammed my email with nonsense, then closed my account.
Oh wow, that sucks, I have started to only use higly regarded exchanges when dealing with fiat due to this kind of crap these small exchanges pull . I don't trust one to not pretend to be hacked.
