Closed account with ongoing bank charges

CAS-***-Z9T9Q2

On 4 November I received a email by Precious to confirm my account was closed successfully. FNB charged monthly fees etc with closure 👍 on the 4th.

On the 12th of November FNB charged bank charges again as well as on the 12th of December after my account was successfully closed and charges charged on the 4th of November.

I then contact a agent to assist me, and they told me my account is still active.

How?? As my account was closed and I logged into the account that was inactive back in November. How can a inactive account made active?
