Complaint / review text:
Quite simply, ACS didn't send me bills for my Perkins Loan. This was due to a number of errors on their part. By chance, I (when I applied for another student loan) found out that my ACS account was 6 months overdue and my credit score had tanked. It was almost impossible to get the issue resolved with ACS. They clearly do not have their act together and have poor customer service.
