Please close my Account Today

I have been trying to get my R13 000 taken from my account without notice by FNB refunded to my account without fail since Friday last week. I have spoken to Tebogo Motaung who insists the money will not be reversed. She gave me her managers name and number Lusiba Mahlala who never answers the phone and is always on voicemail. I have been with FNB for 16 years now. Can someone at FNB please close my account today and give me confirmation. Nothing gets done when I try do it the normal channels and its surprising that I get quick responses through Hello Peter. I need my account closed today please if my money cannot be refunded to my account today. Seems I have lost control of what happens in my account now and it should never be that way. Lets just end the 16 year relationship today.
