Quote from JCVR:
They read me a form letter saying that I could apply again if my employment situtation and account balance changed in the future.
I, for one, appreciate your honesty with your finances.
The solution is to change your financial life to match or exceed whatever they see as minimum standards for you to have a margin account. Since you are not getting anywhere with IB customer service (big surprise there, considering their record), remove all but $720 from your IB account and take the rest elsewhere. Ask me why in a PM.
