Unfortunately, there isn't anything that can be done. Spartan Companies are entirely handled by the Co. leaders. This means they can admit and kick members at their discretion, for any reason or even no reason. This means that there are cases where some Company leaders will troll players by kicking them just before unlocking Achilles. All you can do is look for another company and hope it's better.
