Random Grouo face time calls!

Okay y’all so I’ve. New added in a group ft call that’s be calling nonstop for the last month. Like I’m talking 30 times in under 2 minutes. I’ve contracted Apple many times and they haven’t been any help. They can’t figure out the problem etc but THEY should be able to 🙄 anyways it’s gotten to the point that I’ve now contacted the police and will will be filling a report and hopefully pressing charges if they can figure out the numbers and trace them back. Just wanna know if any else has experienced this? I picked it up today for the first and it’s a bunch of little fucking kids but I honestly don’t think it is I think it’s someone hacking and disguise theme selves. The problem is ALL of these people are blocked but they’re STILL ABLE TO REACH AND CALL ME
