Don't expect TCF from FNB.

FNB continues to surprise me. I settled my loan on 16 May 2018 on my banking app. To my surprise when I logged onto my app lastnight, I noted there was interest charged to the account, and I know that I have settled the account on the 16th May. Seems FNB wants me to be indebted to them. The "NO Service" from FNB gets worse everyday. When I asked you for help FNB you didn't want to help me, and now that I've paid the account in full you go and add I don't know what fees afterwards. FNB just be fair, or doesn't FNB know about TCF?
