Dismal service regarding getting a correct settlement figure for my personal loan that I want to settle early.

Poor service regarding getting a correct settlement figure for my personal loan that I want to settle early. I phoned the Nedbank Lifestyle call centre on the 1st of July because my I want to settle my personal loan early. The call centre agent could not tell me why the balance after my payment was R 256.91 less than the current balance showing and this amount was R 224.96 less than the settlement shown. This means that the actual current balance was R 481.87 less than the settlement amount. on the 1st of July when I wanted to settle the account. The call centre agent said that he was going to query this and then get back to me. I did not receive a call back from him. I phoned again on the 4th of July, and got to speak to another call centre agent, She escalated the issue to her team leader, and to the original call centre agents team leader. The original call centre agent phoned me back within a couple of minutes. He explained that the reason why the balance differed from the current balance was due to the interest change. I asked him if this charge was for the month of June or for the month of July. He could not answer me. he said that he would find out and would let me know. I received no call back again. I then phoned Nedbank's Lifestyle call centre again shortly after the looting started in KZN, and was informed by the call centre agent that they had closed the Lifestyle call centre and most of the branches due to the looting. I said that I would call back once the looting was over and when the Nedbank staff were back at work. I then received an email from *** where Mr Mike Brown explained about the looting and that they had reopened their branches that they could for business. I then phoned and spoke to another call centre agent, and asked to speak to a team leader. This issue was then escalated to a gentleman called Sishen and a couple of days later to a lady called Cindy. Cindy called me back twice to give me progress updates, and I asked her that we please have this issue resolved before the next debit order goes off. I emailed her yesterday, and she rep**** today. In her email she shows current balances with interest, and this is again another R 144.10 and this was in effect from the 20th to the 27th of July. Today is the 30th of July so this amount is again not the correct one. I am very unhappy that I have had to call in nearly every time for progress updates, and to follow up on this issue in an attempt to get it resolved amicably without being **********. I have been a client of Nedbank for more than 30 years, and am really not used to this bad service !!!!!
