Scam activation lock
Hello, I'm pretty new to apple ecosystem, I'm using it for 2 years (at least my macbook). I didn't know that there is a feature Apple has (Find my) so you can "brick" any device where you are logged in with your apple id.
The case:
I decided to move from Intel to M1 mac and bought 13 inch mac and tried to sell my old macbook (intel).
Some time later I got a call from potential buyer (but it was a scammer), he asked me pretty common questions about mac I'm selling and he asked if it's reset. Indeed I reset this mac before selling, so he asked me to check battery health, and he suggested me to enter his apple id credentials so he can check it's working on his side.
After I've entered his credentials my mac just went offline and asked me to enter a pin. Five minutes later he called me again and asked for 150$ to unlock the device. I denied, because he can't guarantee he will unlock it.
After that I've tried to reset apple controller with Apple configurator app (using my new M1 mac). After that pin screen disappeared but when I tried to connect to wifi and start internet recovery then nothing happens (it connects to wifi and just does nothing).
Could you please help me with this?
PS: I have packaging box, payment receipts (I bought it in 2019) and a screenshot with apple id I entered and password I got from the scammer.
