College Of Southern Nevada Took pell grant monies for which I never attented classes and now wants me to pay it back. Las Vegas Nevada

I never took classes at CSN after I had enrolled at this school.

They wanted me to pay them 618.00 dollars for classes and stated 0 pell grant.  Why would I owe for classes I never took nor attended.  They sent mev a saap paper that stated I was in good standing for Spring .

I disputed the 618.00 never heard from them.  In 2013  When I recently decided to go back to classes

I added a new school to my FASHA and did not remove CSN. Not realizing that they resend it out to all on list.

CSN decided after that I owed a overpayment of pell grant in a amount over 2000.00 and send it to a collection agency.  I have been trying to fight this with the school, collection agency, federal pell grant people, etc.  This is keeping me from finishing my education and I am getting no where.  I need to get this school to remove their mistake so I can move forward in my life.
