Capitec Bank Banking App no help with *****

I have encountered a phishing transaction today. I am awaiting a parcel to be delivered to my address in 3-5 days and received a message from The Courier Guy that I need to make a payment of R18 for the fee...as I thought this was legit, I entered my Capitec card details on the site that was attached to the message. First, it did not want to go through because I was waiting for an OTP, so I tried again but received no OTP. All of a sudden, I checked my Capitec Banks App and got a notification that someone purchased 2 items worth over R4000, and I needed to approve it... Thank God, then I only considered that something is really wrong here. I immediately declined the transaction but do feel vulnerable that this bogus Courier Guy site does have all my card details and they can try to make purchases on my behalf anytime now. My main concern was that I could not find any place to report suspected ***** on the Capitecs Banking App. It does not help you warn us about all the pitfalls, but it doesn't have a ***** complaint feature on the app. I tried the WhatsApp no you provided to learn about *****...It is just a robot that wants to teach me all about *****... I needed someone to actually assist me, to tell me what to do when the ***** already happened! I HOPE someone can get back to me to tell me If I will need a new card or account and what my options are.
