Nedbank refusing to close the credit card account

I have settled and closed my credit card with Nedbank on 21.12.2018 after i hassled for two weeks with them to close the account and remove it from my internet banking. Today i am looking at my credit report which they updated on 31.12.2018 that the account is still outstanding shows to be active by the bank.

Get someone to assist on this. my ID 820 ********** 089
