The system is programmed therefore you will charged interest even when the loan is settled

Please calculate my settlement figure as of the 5/07/2022 ,i am tired of explaining my complaint to someone who is clearly not willing to assist Celeste Stanley, today is the 12/07 the complaint was logged on the 5th in order to close my personal loan account .I requested a settlement figure on the 30/06 and also on the 2/07 which was also dated the 30 June 2022,what was my settlement figure for the 5/07 and also why im i still charged insurance when i have paid the principal amount .Celeste you do not own Nedbank and you have no right as how i should complain i am the one who is paying and for you to say this the final call you are closing the call that not how business operate unfortunately. The system is not programmed as you said on the phone .on the 5/07 you said there is a shortfall on R50 today you said it is R405 .why are you charging me interested for the 5/6/7 of July .You said that had I paid the figure quoted for the 7/7 you were going to reimburse me so how does your calculation work when I have paid on the 5/7 and how much is the settlement figure for that day .Celeste you reasoning and complains resolution is questionable. Why charge for the insurance still ?Please i cant deal with Celeste .Nedbank is a big institution not to be able to calculate the settlement figure for the 5/7/2022.There is more interest being added as the loan account is not closed .What an incompetence for just a minor calculation to settle a loan .Celeste you cannot reason like you own the institution who gave you the authority to speak to clients like that what a shame .
