Fun Casino - Delayed payment, ignoring my email and chat

Hi I made my first deposit at fun casino on December 26th, 2016. I got the welcome bonus with my deposit and made it through the wagering requirements to request a withdrawal afterwards. I requested the withdrawal for 0.50000. Which is about $500. There is no live and when it is online they completely ignored me for an hour and they do not respond to my emails. I deposited with Bitcoin which is instant and they sate and withdrawals are instant as well. I would not worry so much if they didn't ignore me on chat and email. I don't know what to do but to come here and ask for Ask Gamblers to help me get my money!
