Unfair billing on fully settled & paid-up account (***)

I worked tirelessly to pay off my debt and close my Woolworths Financial Services account. After paying the full balance, Woolworths provided me with an official Paid-Up Letter confirming that my balance was R0.00 and the account was settled.

To my frustration, Woolworths is now claiming I owe R889.00 on a closed account! When I queried this, they shifted the responsibility to Debt Review / Consumer Friend instead of explaining why they billed charges on an account they already certified as paid up.

I did not make any purchases to incur this R889.00. Woolworths failed to properly close or zero-rate the account after issuing a paid-up letter, allowing unnecessary interest or service fees to accrue, and now expects me to pay for their system oversight.

I demand that Woolworths Financial Services immediately investigate their system charges, reverse this unfair R889.00 fee, update my profile to reflect a R0.00 balance, and stop penalizing customers who have fulfilled their payment obligations in full.
