My iPhone iCloud account was phished
Hello, I wanted to sell my old iPhone, the person who had to buy my phone asked me to enter his iCloud data into my phone, if his steps were normal on my phone he would buy my phone. I believed that when I entered his data in iCloud, he changed his password and demanded money from me to say the password. Please help me, I have all the screenshots I can send.
