This was a charged off loan by ACS. After XXXX plus years of payments no monthly bills were sent to the correct address and no phone calls by them occurred asking for payments. They had cell phone numbers for my son as the recipient of the loan and my self as the cosigner. 
We were never contacted received no default notice. The only reason we are aware of the charge off is because of a credit report that was pulled in the last two weeks. I am more than willing to pay what is due but in the same token I have been personally damaged by erroneous filling by ACS to the credit bureau.
