In the case of rehab, you will only be able to deal with the CA, not the DOE. And that is perfectly acceptable in this instance. Typically, we suggest that you not deal with a CA for the average debt, but a SL is not an average debt. They can and will validate, and they will not goof off. Take it seriously.
Your first step should be to contact the CA at a time when you are prepared and able to discuss the problem rationally and without emotion. Don't let the CA rile you up - it IS their job to collect the debt you owe. Be sure to read up here on rehab and learn all you can before you make that call. I would suggest you read
here for information as well.
