You are in danger.   
It's great that you want to think about others now, but you can only work on the outcome after you make sure you are safe.   

Do whatever you need to do.   Ensure your safety.   Call a friend.  Call the police.  Call your parents.   Tell someone on Reddit where to send the police.  

The BF is manipulative and abusive.  Run.   He took your money.  He removed your choice to leave (kidnapping).   He has you in genuine fear that he will take your phone - then you have less chance to help yourself.  

Help yourself.  Please get help now.  Get the police or friends and get out of there.    
Do not look back.
