Congrats! I don't have a contact for GECRB but hopefully someone will chime in here.
Woo Hoo!! Collections Gone GoneGone!! bye bye.
1) don't know of any contacts, sorry.Keep looking for them.
2) I don't know for sure but, I've read, if you go thru the Fed Rehab program pay as agreed, they will take it out of default, delete the CA and clear all negs like it never happened. You may need to post this question on the student loan board. Oh wait a minute, I see you're in a rehab program...Have you asked if they will delete?if not, ask how they will report after you finished paying.
3)to get the best answer,Start another thread,along with your CS's and post if this is. your only CC or do you have more CC's.
