Don’t know what to do

•K•

So before anything this is not period related but I just want to know if other people have experienced this too. So two days ago i was added to an anonymous group (it was literally called that) early in the morning and people were calling me like at 2 but I was asleep so I didn’t see it until I woke up and when I checked the messages weren’t in English it looked like Indian or something. I thought they probably added me by mistake so I just left the chat and blocked the people that called me. Well today I was up at 4 in the morning because someone was calling me and it’s an unknown number from INDIA and they wanted to FaceTime through WhatsApp so I hang up and go to my chats and I was added AGAIN and the caller had called me like 4 times already so I blocked the chat, all the people that were messaging me and now I’m so scared because this already happened twice and I just want to know if anyone knows how to deal with this. Any help is well received thank you
