CHARGED FOR UNUSED LOAN AMOUNT/AGENT RUDE

I sent an online chat using the FNB app and was 'assisted by Aadiel Saleh who demonstrated no knowledge of what he/she is doing, he decided to close my query while I was chatting. my request was simple, I have asked that they cancel my revolving load with I activated last week Friday, I only used R1000 from the amount and then paid back the R1000 plus the initiation fee of R115. Now the revolving loan statement shows that I still owe R200 and odd rands.

What the hell is that for? cancel your load now and not even think of of charging the R201 that your consultant couldn't even account for or explain.
