Lack of feedback on a paid up account

Good day

My edgars account was settled in full as per statement in August 2020. i got a statement on the 17 September 2020 and noticed that i am been charged admin fees. how can i get charged when the account was zero , now in October , i get threats to settle R70

i have been having a battle and no one seems to be interested to resolve and close the account.

Initial email sent to Nonhlanhla Dlamini 17.09.2020 (Ref ***/GO) which the query was referred to the regional credit office team to resolve.

24.09 Regional team ( Emmanuel Matodzi) claiming that he needed proof of payment even though the statement reflects the payment done in August 2020

All details from Easypay has been sent to confirm payment and to date we have not received a response.

as it stands , we are receiving overdue sms to settle account yet no one is resolving the issues.

we have escalated to RCS and still have not received any feedback

your number that is given to call is not working
