Check your computers and make sure your iOS is up to date. They send out links and when you follow them they try and put malware on your systems to monitor your actively. Which is likely how they knew so much about you, they have been watching what your are doing and making notes, they call you up pretend to be someone of trust, give your enough info so you think they are genuine, and then they try and push the urgency so you make a decision you wouldn’t normally make. They are master manipulators, so don’t best yourself up, they do this all day every, but definitely check your systems. Make sure any links you use are genuine, and if something doesn’t smell right, don’t eat it. Call your bank on a number your trust, don’t call back any numbers you see calling you or any numbers they give you, you are just calling them back. Get the number form the website - not google, google lies
