I have this issue with my student loans. They let it sit for weeks 'in processing' while I accrue interest on it. What am I applying for? IBR. Income based repayment because I'm effectively poor. It just sucks seeing the balance grow and grow and have my credit wrecked, just because they let my paperwork sit in processing. I turn around and re-submit stuff when they ask within a day. For them it's 2-4 weeks between replies. JFC.
