Why is Edgars not closing my account???

I sent Edgars a mail on 4 August 2020 stating that I would like to close my account. They rep**** back saying that I have to pay the final outstanding amount which was R221.93. On the 6 August I paid the full outstanding amount and mailed the payment confirmation to them stating that I no longer owe them money. The next two months I received statements stating that I owed club fees for September and October. I called them on Friday, 16 October to ask why I’m still getting statements from them when my account was settled. I was sent from pillar to post from one department to the next and nothing was sorted!!!!! Now I’m getting messages from a debtor collector department stating that I owe club fees for September and October. I have been a loyal account holder with Edgars for at least 20 years and have never defaulted on a payment. They have lost a customer who had a good credit record and this is the treatment I get. Why is my account not closed yet????
