Club fees and service fees

How hypocritical and one be...they want to help during this pandemic but they charge me for Club membership I did not sign up for...and service fees for something I'm not using...I settled my account in-store on 10 March 2020 thinking that I'm on a zero balance...Then when the lockdown was announced I was happy that I had settled my debt...or so I thought....I received calls stating that I owe club fees and service fees...I query this and every time I was told we will get back to you but no-one ever does...apparently I've been paying club fees for years without noticing...they now say I owe over R300 after I settled my account in March and without making use of their services...Pathetic company...I will close this account and I will make sure I inform everyone I know and in every possible way or platform how pathetic Edcon is...
