Who called from 3254802465

Unknown number. No messsge

I answered the phone and this guy yells ARE YOU THE BUSINESS OWNER. When I said no he again yells GIVE ME THE BUSINESS OWNER. When I asked who's calling, the guy yells an awful curse word and slammed the phone down.

I do Not answer phone numbers that I do not know. But this number calls me many many times a day. 325 480 and several different number types.
How can I stop this?
My son is in prison therefore, I can't block numbers due to the prison selling my number etc. His calls always show up private or unknown and I will answer incase it is him. But all theses other numbers are driving me crazy.
Thank you,
Debra

Called with C. Hodges on CID. Live male answered with offer of Free security installation. I told him what he could do and hung up.

A blunt and rude middle eastern sounding man yelled out....LET ME SPEAK WITH THE BUSINESS OWNER! I asked who is calling and he hung up on me.
