This is the worst student loan service company. I am convinced that the loan balance UHEAA had is incorrect and they are very likely over charging me. The number of loans and amounts, dates on the records they have for me do not match the FSA records, yet, they refuse to correct it. They claim that the FSA records are wrong. The customer service are not helpful at all. No one at UHEAA is helpful. I have been extremely frustrated dealing with the company. The interest rate calculations accumulate like a mortgage rate.
