I borrowed from XXXX towards my XXXX education at a XXXX DC university. While I defaulted on my loan payments in XXXX, I reached a settlement of my debts via a separate debt collection agency in XXXX, which I fulfilled completely by XXXX XXXX, per the settlement agreement. However, the collection agency claimed I still had outstanding debt, and when I asked for them to produce evidence of said debt, they refused. Since then, a handful of rotating debt collection agencies have sequentially attempted to collect this already-settled-and-paid debt. Most recently, I have received phone calls from an agency with no written correspondence to identify the presumed debts.
