I found it [...] safe. [...] one of my wallets I have stored on the websites
Well, a wallet stored on a website is anything, but not safe.
It doesn't matter what service it is, whether its operator is fair and honest or a scammer, it just isn't safe. If I may give you advice, get at least
Electrum – it's fast, yet you always hold all private keys to your coins.
Edit: aubert's screenshot refers to
this event. It's good to read more information about what happened so as one doesn't trust on-line wallet services never again.
