Contacted by GC Services today about an old student loan which I am paying thru a different company that I am paying for this debt. The collector from GC Services said that it was from XXXX XX/XX/XXXX. This is the debt that I am paying through a different compay. 
GC Services can not produce promissory notes or any original documentation to verify this loan. They also took a chunk of my income tax return in XX/XX/XXXX. 
I need some help with this one please.
