Multiplayer

Hey guys, can you please advise? Will my account be permanently banned for using multiple accounts, or are there any other options? This is regarding Heroes of Might and Magic Online. Everything didn't go as planned; I couldn't log into my account, and the loading was endless. I logged in with a different account and tried to contact the admins in the chat, and after that, I was blocked. Now, when I try to log in, it says my account is blocked due to multiple accounts. I didn't even know it was against the rules to run different accounts in the same browser. So, I accidentally broke the rules, and now I don't know what to do. I've written to the admin and support, but there's no response yet. Can anyone suggest what I can do? Should I just forget about the account, or will the ban be temporary?
