I decided to take my chances and send a GW letter to the central office at SC Student Loan Corp. I have two series of 60-90-120 lates on 4 separate TLs that have been paid in full and while it happened 3 & 4 years ago it's still burning my score. Got an unexpected 13 point bump on EQ so I figured I would refresh the report, bam all 4 TLs have been updated with a paid, never late! EX has also updated, just waiting for TU which is always the slowpoke of mine.
Current Score: TU: 674 | EQ: 722 | EX: 717 | Last Inq. 2/16/15...Locked Up in The Garden
