Paid up account still reflected on ITC

I paid up my account in June 2017 and received paid up letter in August 2017 which stated that my records will be updated with ITC. As at today, this balance is still reflected as a default. I even called Discovery today and I was told that a request has been made. I was told the same statement in August and that my records will be updated within 3 to 5 days. It has been months now, no progress.
