Why even use try to use this shady website? Their domain was registered 8 days ago, I have never seen this website anywhere, and they doesn't inspire any confidence at all.
When you are messing with money, you should always use a well-known website that it's proven to be legit - like those that can be found on the
BitcoinCash.org website, and not try to use a random website.
I am almost sure that your coins are gone. If you still want a
real web wallet that supports BCH, use
bcc-wallet.btc.com next time.
