A very angry and disgruntled client.

So I took out a loan with African bank, more than 2 years ago, I have been paying them for more 2 years, and when calling them now they telling me my account has been handed over, so I called the branch, then they referred me to the head office, and the head office gave me the number for the legal department, called them telling them that my monthly debits have been successful for the past 2 years, and the loan should be completed, then got a response and was told by the lady in the head office that the amount owing is now more than the actual loan itself, even though I've been paying, she told me I can do what I must and I will have to pay legal fees, their monthly debits and the amount to concept recoveries. I then ask how can I now pay the loan all over again as now I need to pay 3 departments to take it off from my name, and she said well we won't update the credit buerue until you pay this amount, I have sent emails, including monthly statements showing the debits are successful and they don't respond. called there legal department explained again and telling there is something very wrong and there must be a discrepancy on their books, and then asked for the guys name, then the call got dropped in my face, then called again and asked for a manager, was told the manager Themba refuses to speak to me. So what do I do now? During this time in which coloured people are already struggling to make ends meat, I am being harassed for not paying, even though i am paying. should i pay this one account for the rest of my life seeing that they just refuse to assist and just want my money even if I've already paid? I have escalated to the national credit buerue and they too cant assist. The level of unprofessionalism is beyond me, how do one fight to pay an account and get told do what u want to.
