Shocking service

I don't even know where to begin to explain my frustration. I had a loan I took many years ago. Due to circumstance the account was handed over to Concept Recoveries and I have been paying monthly to them ever since. I recently contacted Concept to obtain a settlement letter and upon receipt of the letter I settled the account in full. I was then provided a paid up letter. I have now submitted the paid up letter to Transunion who have advised that African Bank are disputing that the loan is paid up after me settling it. I decided to call African Bank to find out what is going on. The guy on the line wanted me to confirm a cellphone number that I used over 10 years ago. Of course I could not remember it and was advised I need to go into a branch. Today I went into your branch at The Atrium in Overport Durban who advised they also cannot help me as my fingerprint doesn't work and I should go to home affairs. What nonsense is this? I go to Capitec, FNB and many other places where I insert my fingerprint and this is the first time I'm being advised of this. Now you tell me what I must do?? I can't get help when I call, I can't get help at a branch and I have paid up the account and I want it removed from ITC but can't because African Bank want me to go to home affairs??? I am a working person I don't have time to go to home affairs just for you to update your records. Surely there should be a way of updating this we are not living in 1903. I am absolutely annoyed and angry at the fact that when you wanted your money I was hounded for it but when it's time for you to do your part there is red tape. Typical to expect this in our country where everywhere we go as consumers we are given ****py service and the run around. I expect this to get some kind of resolution or else I will make use of all social platforms and naming the people in your organization who are not even willing to assist. Pathetic service honestly
