Does this sound like their rehab program is applicable to private student loans?
One missed payment does not equal default (however, a missed payment appears on your credit history and may affect your ability to obtain credit in the future). A student loan can go into default after 120 days of nonpayment for private loans and 270 days of nonpayment for federal loans.
If your student loan account is delinquent and you are trying to prevent a loan/loans from entering default, please contact our Default Prevention department

The Default Rehabilitation Program allows defaulted student loan borrowers who have established satisfactory repayment after default to remove the defaulted status completely from their AES-guaranteed loan account(s) and credit report histories.
