Bad Correspondence

I went to ABSA branch in Kraaifontein towards the end of February 2018 to close my Check account because of high account fees. I went to the client service and I was told that I needed to go to the cashier and pay an amount of R72 and it was not explained to me what after that and I immediately went to pay and even when I got to the cashier explained what I wanted to do. They confirmed the amount I had to pay and I payed and left. Nobody explained to me that there was more steps I needed to follow and now Im getting calls that I owe ABSA an amount of R1300 for my check account which I know I went there to close it. And the consultant I spoke to on the phone when I rep**** on the SMS I received from ABSA insist that I have to pay the amount. I left my house going to ABSA to end the nightmare of ridiculus charges and it seems as if it will never end
