FNB Not Processing my refund

I accidently transferred money from my main account to an old credit card account (not sure why the credit card is still ono my profile). I contacted FNB on 30/12/2024 and was told a refund request was submitted and I must wait 15 days. On 7/1/2025 I did a follow up and was informed to send teh refund request on a signed letter to *** and *** and to date I am still waiting for feedback. I called again today and spoke to Fhatuwani Malulumavhi in the Debt Review Dpt and she informed me to email *** as they do not have a direct number even though she can see the money in the old credit card account.
