I do not know what are the details of your story, but if the site is hacked, how do you expect them to return the money to you? Currency mixing sites are not the same as platforms, and the amounts in hot wallets may be few or many depending on the mixing method.
If you are sure that the site has been hacked, then the site’s administration will announce that. Otherwise, either you have been scammed by the site or that you used a different site (phishing site.)
