Well our staff team is very active, though we can't be around 24/7 to help out one Jailbreak server, since we have many other servers and places we need to administrate, including other Jailbreak servers. I'd reccomend if CallAdmin isn't sufficient enough for you in terms of contacting staff that you join our Discord server and request help there, or contact staff directly over Steam or Discord.
Anyway, to apply you need to fill out our Staff Application, which is on these forums and I won't be linking because they're easy to find. Though we have high standards, put your most effort into making a good application, being active in our community platforms, and overall becoming a good presence and showing you're a good pick for the staff team.
