I say you either sue them or go to a reporter, twitter, facebook.
If you manage to go to a reporter, they would be more inclined to solve things with you as that would make negative marketing.
I don't think attempting to sue them is going to get you anywhere as you will end up just spending more money in legal fees. Has no one even specified why your IP was banned?
So let me get this straight, you have not tried to withdraw your funds, so they should in essence just be sitting in the funds section when you log into your account right? Also, how do you know that your support tickets are being deleted?
here is a video, sorry its it long but its a little info about what is happening
About 2 1/2 weeks ago I accidentally clicked on the 'lost device' when i was logging in on my iPhone. i was instantly locked out for two weeks with no confirmation, or warning. I only got an email stating that 2FA was requested unlock. I contacted them and they said wait two weeks. after 2weeks i was able to login and see my funds (thank goodness) but i was not able to withdrawal any coins at all. ACCOUNT DENIED. CONTACT SUPPORT. is the message i get in red if i try to withdraw any coins. At first my Support login help desk was DISABLED. So i used a new email and i created a new help ticket. they told me the some old think word for word copy and paste style. So i ask how and when can i withdraw. that is when they deleted my support tickets. and some they mark red and 'resolved' no reply or explanation. Furthermore they take the time to delete my tickets and or mark resolved, but so response. OK so then someone suggested i send message in russian in the Russian chat (which i didn't even know about) Then after a few attempts when the screen said they were online i asked ' Please admin, i need help can't withdraw. And to my surprise i got a response from support. They asked me the problem...grrr and i explained nicely. And they didn't reply i said let me know if you need screen shots. and then they deleted the support ticket. I tried to ask for help nicely in the russian chat and then my account was/is banned. can't login or anything at all. they still haven't answered my support tickets
