Funds accidentally transferred to a credit card account

At one stage I was under debt review, but all my debts has been settled some time ago, including the FNB Credit Card. I have contacted FNB to close the account and remove it from my Online Profile. To date this has not been done. I accidentally transferred R977 from my Savings Pocket to the credit card in error. Now I am struggling to get the money transferred back. I have tried to contact FNB only to be told that my account is at Legal. I am unable to get hold of the Legal Dept. I have logged a complaint twice and still waiting on a response from FNB. Last complaints reference number is ***.

Can someone please help!!!!!!
