Caller: I don't know

I meet him in the next level gym noble park. He ask my number and i gave it to him bcs i am afraid. Then he always call me but i never pick up. Once he called me while i'm hanging out with my boyfriend. It looks suspicious so my bf ask me to call him, then this man said he wants pay me for sex. He did harrasment to me via phone call and make me fight with my bf.
