FNB IS THE WORST WITH REFUNDS AND IT’S JUST *****.

I took out a personal loan with FNB and inFeb 2023 I settled my loan but I was still debited for the same loan I settled… I called the loans department and even went to the branch in Clearwater Roodepoort but till today I have received my refund and I was still charged interest..I am banking with them so I wanna switch banks because they do as they please.
