Seriously Sallie?

Nothing much is new but I have to vent a little:
I made a payment to Sallie Mae over the weekend and it's STILL not posted on their website. Even if I wanted to make a payment before even MORE interest racked up, I couldn't. The period between making a payment and having it register on their website means that I can't even access the "pay now" page. That page breaks down each loan for you to see the exact amounts you still owe and how much of that is interest accrued. All I really want to do at this point is after I make a payment, I want to see how much my loan went down and see a pretty little $0 next to "interest accrued". Even after sucking all my money out of me, they're also sucking any minor rewards out of me too, which is making this loan thing really suck.
