A few days ago i was hacked. The person who hacked ny account changed my email and phone number on my account. I got a email saying the emails been changed so i reverted the change. Instagram then asks me to confirm i own this account asking me to send a code to the email and phone number but its the same email address and phone number i registered with but i no longer have access to the email and phone number ib registered with. Then i reported it to instagram and they asked me to send a picture of myself with a code and my username and full name. I did that then they sent me a password reset link so i changed my password but everytime i logged in a "confirm you own this account" message keeps popping up i couldn't get past it. Then the person who hacked it changed the password, hes able to reset it because when the accounts linked to hes contact details but when either or us try sign in it asks for mine. I don't know what to do. Can you help me out please? I need to reset my password again and I need the "confirm you own this account" message to go.
