Who called from 5402122851

Did not leave message. Using local number but I found it was an IP computer caller. Scam

I just received a call at 6:05pm on march 27th. Came up as local culpepper va.   No response when I answered.  Re added my number to do not call list 90 days ago but that's not helping

They kept calling me

They said "hello, can you hear me?".

Calls repeatedly. Hangs up when I answer. Called back, voice prompt states "does not accept calls from blocked numbers". Daily harassment, I've stored each call in log for report.
