Caller: Message from female?

Had a message from this number replying to an ad I had on Locanto. They made out they were a female. Wouldn't answer any of my questions

this guy is a lunatic, told him i couldnt help him and kept calling over and over and over again.

He rang me and repeatedly asked if I could hear him. When I responded yes, he proceeded to shout through the receiver about my "interrupting" him, swearing and use strongly inflammatory slurs.
I assume it was a wrong number but it was pretty upsetting and scary to be on the receiving end. When I hung up, he proceeded to call back multiple times until I was able to block his number.

Guy rang and said he’s responding to missed call and proceeded to ask my identity. Hung up when I refused to tell him.
