Elite Current Account Standard Bank

I had an elite current account with standard bank that had an overdraft. I couldnt pay it on time and was handed over I dealt directly with Phindile from Findlay & Niemeyer Call centre. I paid the amount given to me and received an email from Phindile that the account is now closed. However I received a Statement from Standard bank claiming I owe R21 000. I called spoke to someone and she said I should send all the info and she will sort it out. I have now receive a Statement again and I still owe R21 000 after I was handed over dealt with the debt through the collection agency paid it up and Standardbank never closed the account it seems. I need this account closed ASAP.
