Called and left no message, so they got blocked.  I'm sure they'll call back with the same area code, just a different number.

They called and i said hello several times and no one answered, they eventually hung up.

I answered a call, to my cell phone, from this number this morning.
I did not recognize the number as being from friends or family.
This cell phone is used for Emergency Response only and is not used for business or socializing.
I suspected that it was a robo call so I answered with "Yes?" instead of "Hello".
This tends to confuse robo-callers. They do not recognize "yes" as a greeting.
There was a long pause. Then the caller said that she was Samantha Harper and started a spiel about auto insurance.
You could tell that it was an automated voice.
I hung up.
I have not recently solicited insurance of any kind. I have had the same insurance provider for decades.
I also thought robo calls were illegal Texas.
We need a"SCAM" option in the call type selection below.

Has called twice a week for the last 3 weeks. Never leaves a message. They are now blocked

Just block this number now.  Save yourself the effort of dealing with them
