FNB Personal Loan Settlement Dispute

I phoned the FNB personal loan department to get a settlement amount for my personal loan. After a long verification process with a very rude agent I requested my settlement amount. The agent gave me a settlement amount of almost R2200 more than the outstanding amount. I questioned the agent why the amount are so much higher and asked him if there are any early settlement penalties whereby he answered yes. I quoted the agent that on FNB's website they state that there are no early settlement penalty whereby he responded that he is unaware of this. After this the agent tried to end the call immediately. He then transferred me to the debt department for an explanation. Once again I was on hold for 7 minutes and had to do the whole verification process again. The agent could not give me a valid explanation of the amount and said that she will get her manager to speak to me, once again placed on hold and after 10 minutes the call were cut.

I phoned back again and did to verification process on the phone keypad. The agent answered the call and once again asked me for verification whereby I refused. The agent put me on hold again and after +- 8 min a "manager" called Marvin answered my call. Marvin gave me a explanation that the 2000+ difference are for 10 days interest, I immediate stopped him and explained that as per my monthly statement my total interest are R2200, how does he explain that for 10 days they are charging me R2000+ interest, once again no valid explanation?

I then asked Marvin which amount should be paid as at this point I had three different amounts 1)Total outstanding, 2) Settlement amount as per agent and 3) Settlement amount as per FNB app. He instructed me that if I pay the settlement amount as per the FNB app before close of business that will be the correct amount. He also commented that if I make the payment as per the app, I should phone back in the next two days to ensure that the loan are settled. This is shocking service, why should I phone back????

I made the payment as per the FNB app within the next 30 minutes after talking to Marvin. After the payment were done as of this moment the app shows that there are still a settlement amount due.

I will appreciate if some one within FNB can assist to get this sorted asap.
