Refund delayed

I was put on Debt review in 2019 and July 2023 I paid my last instalment owed to them, and by accident paid in August an amount of R4000. I reported it to Consumer Friend and they confirmed that it will take 30 days to refund. On following up today again they claim they made a mistake and refund is going to take another 30 days. REALLY!!! I would appreciate it if Woolworths can step in and refund me asap.
