Make an additional post addressing the stake owners if the issue still persists because I do think that it will still take some time to get this done and if they do have live chat contact them again.
Well other than that you should message them here if they do not listen or ignores there is always scam section where you can message or make a new post but at the end of the day the site is good and I do think that they would for sure resolve this soon.
Also make sure you follow all the rules etc there are actually tons of them which makes you eligible for it. Depends on site to site.
I do hope this gets resolved.

Stay away from this site! As soon as you start winning, the problems begin!
You should present some proof of such accusations since the site is well reputed and this is unprofessional to criticize if you don't have solid grounds. Take the example above the guy presented the statement with his name and also the screenshots. Which can be looked into and resolved.
