Dealing with your lender or servicer: Student loan

I was on the SAVE pause forbearance. Nelnet contacted me during that forbearance stating I owed a payment. That information was incorrect. Based on that error I switched to IBR. This resulted in delinquency and denial of forbearance options until I escalated to a supervisor. A 12-month forbearance was ultimately granted but only after significant pushback. I am filing this complaint to document the servicer error that initiated this situation.
