APPLE SECURITY NOT AS GOOD AS THEY CLAIM IT TO BE

On the 15/08/2020 my iphone 11 Pro Max was ****** around 11:00am, i immediately went to a Vodacom store, got the phone "blacklisted" "hard locked" received an ITC number and did a sim swap. the phone had been switched off. At around 17:15 i received a notification that the phone has been switched on and "discoverable" through Find my iPhone. we tried but the "app" wasnt working. At this point i need to mention that, the sim had been swapped, and you need a pin for the sim card, a passcode to open the phone. But even with all the reassurance from Apple that the phone is the safest in the world, after a sim swap, a hard lock and black listing, the people whom had ****** the phone managed to get into my Uber account and rented an Uber, ordered Uber Eats and the best is, accessed my FNB app that also requires a username and password and withdrew a large sum of money. NOW I NEED APPLE TO EXPLAIN HOW THIS HAPPENED WITH ALL THEIR SECURITY PROMISES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
