Late Payments reported from Loan servicer no longer in servi

Hello,
i became 60 and 120 days past due on 3 Student Loans Almost 8 years ago. The accounts were handled and reported late by a student loan servicer who is no longer in business. Later on, they were transferred to my current servicer who i submitted a goodwill adjustment request, but got notification back from them that since they were not the ones to report it late, there is nothing I could do to get this adjusted. IS there anything else I can do? These late payments are effecting me and are the only thing showing late on my credit report. These loans have since then been gone into deferment as im currently in college.
