Who wants $130.00?

I can't make a payment on my student loan this month. I want to make my payment. I have the money to make a payment. BUT MY STUDENT LOAN COMPANY SOLD/TRANSFERRED MY LOAN TO ANOTHER PARTY AND NOW I HAVE NO IDEA WHERE IT IS! I logged on tonight to pay my loan, since it is due tomorrow, and it says I can't make a payment because I no longer have a balance with them. As of Tuesday I did. But today I don't. And I have no idea whom to pay. And now I'm going to get punished for late payment because, right now, I have no idea where my loan even is. GRRR!!!! No respite tonight - only a very frustrated Jessie.
