You can change the default world by changing the "level name" option over in the Settings tab near the top of the panel. If this is a bit confusing you, check out this video linked below to learn how to do it.
 

You can speed up that hour by force hibernating it in the "Danger Zone" tab near the top. That should force stop your server and will allow you to instantly start the server back up with the new plan you bought.

You can give yourself permissions by OPing yourself from the panel. There should be a box called "Server Commands" where you can type commands in. Simply type /op (your username) to give yourself permissions.
You can also check out a YouTube tutorial for that here: 
 

Please make sure you're using the IP bedrock.minehut.com and the port 19132. Once you join that IP, you can use /join (server name) in chat to join your server.

Hey there, sorry about the inconvenience! I looked a bit into your situation and it seems like we did unsuspend the server name you provided in the appeal, the main issue looks like that you changed the name before it was unsuspended and you didn’t notify us what you changed it to, which I presume is why it never went through.
 
What is the current server name?

You could try installing the Essentials plugin. I know that plugin has a /jail command or similar.

That happens sometimes, we're currently using a service that has been having some issues recently. I would check the https://transfer.sh website to see if it's up, and if it is the command should work. Hopefully they fix their up time issues soon, but for now just wait until the website is online and then type the command. Sorry about the inconvenience.
