For those who recall, I few months back, after I had paid off my last SL, I got a call from SLMA for a late...the problem being that I actually had a credit (they owed me!!!)
Got a letter apologizing for the hiccups, a chack for the credit (which was actually more than the few cents that it looked like, due to overpaid stuff somewhere in the past), and the CRAs are showing PIF Paid as agreed, never late...and a nice boost in scores, to boot!
Now, a few breaths before I start applying to grad schools...
