Has anyone ever had this happen or know what it is ?? Has my phone been hacked ? Went into my I cal and saw this in my Calendar. In green letters your account has been blocked we will delete all photos and videos ?

this is a scam. you clicked on something that added a cal account and then this happens. pretty common but easy to remove in your mail accounts setting

Go to your mail settings. Go to accounts. And delete the account that doesn’t belong there. This is a known issue with calendar through Apple. I used to work for Apple and helped people clear this stuff all the time.

This is from your mail. Check your spam and delete those emails

Seems to be a scam
