Credit card (non)service

Had a 12 month subscription service paid once-off via CC since last year October . CC expired in Nov 2019. Got a message from ABSA on the 26/27th Oct 2020, indicating that an amount has not been debited, due to expiration of CC. Which is fine. I went to the vendor's site and terminated the service permanently. Couple of days later I check my CC statement and the full amount has gone through on the 28th !! . I emailed ABSA now twice about this, and everytime I'm being told that that C-***2 "We confirm that the transaction for ******** processed on 27 October 2020 did not go through. We confirm that the transaction was declined due to the fact that it was processed on your expired card" and C-***9 "We confirm that the transaction for ********* processed on 27 October 2020 did not go through. You are welcome to check your statement on latest transactions on internet banking or at the nearest Absa branch."

.. and every time the call is being closed . I've left my contact number on both occassions, but that's just being ignored
