Complaint Lodged with Credit Ombudsman Due to SSDA's Poor Service

My husband had an account with SSDA, which he settled in full on the 3rd of August and supp**** them with all the proof they need as requested. After almost 2 months and multiple emails, phone calls, and WhatsApp chats, we still are not able to obtain a paid-up letter from this company. To add to the frustration, fees have kept accruing on the already settled account incorrectly, and now their systems show we still owe them money. Furthermore, this account still persists on my husband's credit profile, preventing us from financing anything else. I've lodged a formal complaint with the Credit Ombudsman and trust they will be more effective at resolving this issue. We have honored our side of the agreement to the fullest extent, and SSDA simply cannot do the same.
