Genesis Lending Student Loan Complaint

Genesis Lending Student loan department,

Non-federal student loan Dealing with my lender or servicer Received bad information about my loan Washington

I took a loan out with Genesis Lending to attend - - in -, WA and paid it off shortly after graduating. I was told they had been sued and students within a certain time frame were eligible for partial refunds. When I tried to contact them to see if I was eligible for a refund they told me they had no record of my account. What more can I do before contacting a lawyer to pursue a lawsuit?
