Clear the bogus arrears on my account!!

I am very unhappy about you guys and how you have inconvinienced me after settling the debt and receiving a letter that I owe nothing. I settled the debt in December 2020 then all of a sudden in February I have an outstanding debt of R85.00, you went to the extreme to keep it there until it was an overdue amount. Tell me what exactly is it for? I was given a one day settlement amount which was paid for a Standard Bank account to another Standard Bank account which was same day clearance and no additional fees should have been attracted. Kindly update your records as this is showing as an owing amount on the bureau yet I owe absolutely nothing!!! I will await a new letter advising that this has been sorted and I do not owe Nimble nor Direct axis a cent!!
