NuDebt Management Nightmarish Experience

I am currently having a nightmarish experience with Nu Debt Management. About 2 years ago I paid my 24th installment to an MTN contract and thought when I had paid my last amount that was the end of the Contract. At the end of last year I saw an sms saying some NuDebt company required I settle my MTN account. I had never heard of NuDebt and was not aware that MTN had conitnued to charge me despite paying my last installment so I thought it was a **** until I went to MTN around 9 January 2025 to open a new account and they told me I had a hold on my name. In the days to come I found out that MTN was registering an amount outstanding of about R1 650 owed but NuDebt gave me a settlement amount of R 3 030.00 to pay. As I need ed the new account urgently I paid the R3030.00. I was then told that the reference I had used on the transaction was incorrect even though I had been given it by the staff at NuDebt and this was delaying the process of allocation. They literally have issues assigning monies to accounts even though you call them and give them all the info they need, they cannot just say on their system this person paid this seemingly and that takes 21 days. I have called them many times to try sort this out as I have an urgent need to get this new MTN account but seemingly they cannot do the right thing inside. The issue was escalated to their "leaders" and this is where it is stuck now. The leaders do not take calls nor recieve emails and yet are the people who can assist. The poor agents who recieve our calls and are responsible for assisting us cannot do anything when there is such an issue and obviously we call them as clients and all you get is "there's nothing I can do but to talk to my leader". I must say though, the lady who is an Agent there is forth coming and helpful and has tried her best. The organisation and how it works and particularly the roles played by these leaders and senior staff is sinking that whole ship at NuDebt and I am not surprised to come here and find so many people with issues with this company. It's terrible
