My loan was sold to UHEAA from ACS. I noticed some accounting data re my account on line that has led me to question the interest rate I am actually paying. It appears it may be as much as 29%. That is greatly in excess of the amount I agreed to pay when I originally made these college loans. I have never been late with a payment and it appears that I have never given UHEAA any reason to escalate my interest. I called numerous times and never was successful in reaching a human being. I wrote an email to UHEAA on their "contact us" site requesting the interest rate I am supposed to pay. I have not received an answer. This makes me suspicious.
I want a living human being capable of giving accurate answers to me to speak with me. My next step may be to compel UHEAA to provide answers to me through the Court System. I find the standard UHEAA apology to be specious. Call me. Edward R. Hanson, Jr.
