Phone stolen and apple ID password changed and no access to phone number
I am contacting through my family members apple ID and username. Currently I live in Kenya and my phone got stolen last week. According to a notification I received earlier this week, my phone has been located in England. They had already changed my phone password and I had forgotten the email for my Apple ID until my family member gotten an email claiming they had changed my apple ID password. I cannot verify or receive text messages to this number as it was connected to my dutch phone number, which is where im from. The Dutch sim card was in my phone and i had a kenyan E-sim, so they must have changed my apple ID using my dutch sim card to which the account was connected. I now am unable to access my apple ID as they have changed the password and now have access to everything on my phone. I hope you can help me to block my apple ID so they no longer have access.
