Edgars- very bad customer service and staff doesnt know whats going on

I payed the off my account to the balance of zero in Aug 2020, I purchased nothing further and end Sep I got a balance for R175 to be payed for admin and Edgars Club. Admin fee for what? You did absolutely nothing on my account,no activity but charging me admin fee. Ive been an account holder for over 10 yrs and to this day hve I never gotten 1 benefit of Edgars club- not even a bday voucher. I called them wanting to cancel. First of all, I didnt sign or agree to any new and increased admin fees when this new company bought Edgars. They said for Edgars club benefits I should go instore- I did that and no one knows a thing- I called and was put through to 4 different departments and still no one knew a thing. When calling I said I wanted to close acc and they said I need to pay admin fees-for what? There was no activity do no need for an admin fee? I also said Ill pay the admin fee if I can get the last 10 yrs bday vouchers they didnt send and I payed for Edgars club every month. They said the will call me back and again ots been 2 weeks and Im still waiting, again they sent me a new statement end of Oct with another fee on but there has been no activity. Waiting for someone to call me back
