Cannot close my account

My partner and I have immigrated. I had to pay my rental vehicle on the last day of my stay and then boarded my flight hence I could not close my account before I left.<br> <br> I have now tried to contact the bank serval times but for some reason my card verification will not go through over my iPhone key pad, and I also sent Chantal Naidoo ( apparently my personal banker) a mail off my internet banking ,I have also asked on of the bankers to email Chantel to assist ( Nomhle Ngubeni) she still has not gotten back to me. <br> <br> My account shows R6000 in outstanding debits and now reflects -R4000 that i need to pay into the account but an available balance of R1500 +- ?! And we starting a new month so now I'll be charge for an account a no longer require and can administrate as no one gets back to me?! <br> All I want to is the right thing and sort it out but apparently it's to much for Fnb to handle.
