Extremely Poor Service from Nudebt management! Stay away!!!!!

Some time ago, I fell behind on my MTN contract payments due to financial difficulties. Despite this, I continued to make reduced payments toward the outstanding balance. Eventually, my MTN account was handed over to NuDebt for collection. I then entered into a formal repayment arrangement with NuDebt and continued to make regular monthly payments as agreed. In March 2025, I contacted NuDebt to inquire about my account status and the remaining balance. To my surprise, I was informed that the account had been settled four months prior. However, I had not received any communication from NuDebt confirming that the account was settled. Despite the account being closed, NuDebt continued to collect monthly payments from me. As a result, I have overpaid an amount of R2,392.31. I have since been trying to recover this overpayment, but my efforts have been unsuccessful. I have contacted NuDebt on a weekly basis for several months, yet there has been no resolution or refund issued to date. I deeply regret not dealing directly with MTN regarding this matter. The lack of communication and accountability in this situation is unacceptable and has caused me significant frustration. I kindly urge you to investigate this matter urgently and process the refund without further delay!
