Ridiculous admin/service fees on ABSA creditcard

Dear ABSA. I have a creditcard with you. I havent used it at all for 2 months. Yet at the end of each month I get a sms from ABSA saying that there is an outstanding amount due on my creditcard. Not with much. Usually around R60 to R80. So without me using my creditcard you charge me an admin fee or service fee of whatever fee every month. Yes I want to cancel my card. But NO i am not going to the bank during the lockdown period.
