REFUSES TO CANCEL LOAN ACCOUNT AFTER SETTLED

I requested a settlement amount from FNB for my RCP loan account. I was contacted by a consultant given the amount without accurate information regarding payment method. I then had to jump through hoops to eventually get clarity. I paid the settlement amount given and up till now after 2 [Email Removed] complaints logged and after speaking to more than 1 manager the loan account is still active accumulating interest charges which they expect me to pay but this is due to NO fault of my own. I am honestly appalled at the low degrading customer service received from this bank. I just want to get this settled and close all accounts active with them.
