Edgars account received 7 months after having settled and closed the account

Hi I settled my Edgars account and requested that the account be closed in it's totality i.e. including club fees. Low and behold, I received a statement indicating that I still owed the organisation R45.88, for club fees. I proceeded to the Southgate branch where instead of arguing, I paid the R45.88 (23 October 2020). The staff at the Southgate branch called the club membership entity and allowed me to speak to them. It was understood and agreed that this was the final settlement. On 12 May 2021, 7 months later, I received a statement on email indicating that I owe them R92.62.
