iv had to wait 3 weeks for one of my appeals, i recommend emailing them to the parents jagex you will most likely get a response in less than 2 days. I have gotten accounts unbanned this way.
Good luck bro
kay im guessing its not good use,
just keep trying mate. Email them and make up some good story say something like "I know this email is only for parents but i feel my appeal was not well handled i have even heard some appeal are answered by bots and for all the time i have spent in runescape i feel i diserve better....blah....blah.."
Iv been denied after appeals and tried emailing them and my account was unbanned.
