Who called from 3052304072

Calls and never leaves a message on my answering machine. Who are they???

Wants you to donate money for police something or another. Sounds like a person says hello, then immediately pushes a button that starts a recording. I hung up after the first sentence when I got no response to my "no, thank you."

All calls from 305 area code are scams...either police fund donations or senior medic alert. I just put whole area code in my call blocker.

I also have a call blocker....and I put in the entire number. How do you just put the area code int?
Tks
