Can you provide a screenshot showing that your account is inaccessible? Perhaps also the error message when you're trying to recover the account with OTP [the code being censored, of course]? I can see their rep was online few days ago and recently changed their email address. I'll try to invite them here.
This is what I get when trying to log in:

https://i.ibb.co/LSPqDYp/recovery.jpgI played there for a few months and logged in with no issues until yesterday.
A few days later I try to log into website and it tells me my credentials are invalid. They have a system to recover the account using a unique code given only once so I try to do that, but it tells me the code is invalid for the username.
Obviously they locked your account and you can not recover it until they unlock it. Contacting support and getting no response is frustrating. You are talking about hack, how do you know or it's just and argument you have in mind.
Just an argument. It's impossible to change passwords on there without the recovery code, and the code itself can't be changed.
