I have a derog. (Charge off), and the original creditor has agreed to change the entry to pays as agreed, no lates etc in exchange for payment in full. The amount listed on my credit report is the amount that I assumed I would have to pay in full. However, the OC is now saying that interest was added to the original amount (not showing on credit report), so in order to change the listing, I need to pay the interest also. I was under the assumption that once something was charged off, that interest could not be added thereafter. Does anyone know about this type of thing?
