Poor response after trying to report *****

I am currently abroad and noticed three ********** transactions on my credit card. All three transactions were for 01 Mar 2020 and was still uncleared. I immediately used my banking app to cancel the card and tried to get ABSA to call me back urgently.There response was that they can't call me back on an international number and I can't be contacted on my South African cell no either.If that's the case , why not ? And why then not communicate via e-mail or the banking app. All I really want is to confirm that these transactions were stopped and what is going to happen with the new card as I won't be able to collect it just yet. Even after cancelling the credit card one gets no confirmation via email or the app that the card was cancelled.
