Incorrect Billing

I am so disappointed by the service provided by Game/RCS. I've been having an account with Game/RCS and after receiving my August 2024 statement i paid my statement in full. For September 2024 i did not pay as i know i have settled the account but due to the service fee of around R67.00 that is charged on my Game/RCS account i got calls from RCS and they advised that my account is in arrears of around R900.00. How possible to owe this much in 2 months after settling the account in full?

I sent my complaint to Game/RCS complaint department relating my query and i got automated response that they aim to have mycomplaint responded to within 48 hours which they took time to provide feedback. After receiving email feedback from Game/RCS i responded back to inform them that i am not in agreement with what they say i owe and have requested for my account to be reconciled and provide breakdown of what they say i owe. To date i have not receive feedback from Game/RCS except for the harrasment calls from their consultants more that 5 times a day.

Can i request that the complaints department at Game/RCS look into this matter, reconcile the account and provide feedback so that i can pay what is due.
