Pioneer Credit Recovery - don't fall for them!

Pioneer Credit Recovery claims to be associated with Direct Loans and the US Dept. of Education. They have been harassing me for at least 3 months on old defaulted student loans from 2004. They are claiming they can garnish my wages, or my tax refunds if money isn't handed over immediately. All they seem to be interested in is getting my checking account information so they can enroll me in a 'debt rehabilitation program' where they would automatically pull $97 a month from my checking account every month for a minimum of nine months. It may not seem like a huge amount, but my family and I are low-income, and we currently live on less than $1000 a month.

I want to pay these loans back, but I don't know if they are valid, as all my student loans have been with Great Lakes (who I am currently in hardship deferment with). I haven't been in school since 2005, when I gave birth and became a stay-at-home mom to my almost four year old son.

Calling PCR does no good, as every time I speak with someone, I get a different story and a different attempt to get money from me. I have called Direct Loans AND the US Dept. of Education, both of whom claim not to be able to tell me anything other than my supposed 'loan' is being handled by PCR, and I have to go through them. I tried to go to PCR's website, and it has nothing but an error message and a blank page. And I'm still getting phone calls on a weekly basis, even though I have requested to be removed from the call list while I research the authenticity of these loans.
