Unable to get my refund of R4749 from Nimble Group

After standard banded my account to Nimble, for outstanding amount recovery, Nimble's agent offered me a discount, which I paid in installments. Because Nimble was the only thing I was paying from my bank account, on 28th July 2025, while intending to pay my student account, I mistakenly made a payment of R4,999 into the Nimble Credit Solutions account instead of my student account. The correct payment to Nimble should have been R250. This resulted in an overpayment of R4,749 (R4,999 - R250).

Nimble acknowledged the error and, in addition to confirming that my account was settled and would be closed. I was also assured that I would be refunded the overpaid amount of R4,749.

Despite multiple attempts to follow up since then, I have not received the refund. On each occasion, the agent on the phone has promised that the refund is being processed, but no funds have been returned to my account. My last communication with her was on 18th Sept 2025, to which agent on the phone also sounded surprised that I haven't received my refund. They did not come back to me as usual.

I have

Proof of payment showing the R4,999 transfer to Nimble Credit Solutions.

Evidence that my account with Nimble has been settled and closed.

Email conversations like asking me ID to swift process my refund

Now no one is saying anything anymore

I kindly request that you investigate this matter as a matter of urgency and facilitate the return of my R4,749.

I also believe a credit corrector appointed by a first financial institute, such as Standard Bank, has a responsibility to ensure that the agency handles client funds and complaints with integrity.
