Refusal of account transparency - DMC

I have an ongoing query regarding my The Fix / Foschini Group account with DMC Evolution, currently left unresolved. DMC claims an amount of R6,868.37, reflecting a principal debt of R3,434.19 and an unexplained R6,868.37 categorized under "Other" with 0% interest. Despite multiple follow-ups via helpdesk and live chat, I continue to receive automated statements that do not address my request for an itemized breakdown. Consumer Friend previously advised that this account was terminated for non-payment in September 2023, yet DMC provides no transaction history or supporting documentation to substantiate the current balance. I require the following to resolve the matter: An itemized breakdown of the R6,868.37 "Other" charge. A complete transaction history and original account records.

I am requesting a substantive written response rather than a repetitive statement. If this remains unresolved, I will be left with no choice but to escalate the matter to the National Credit Regulator (NCR).
