Didn't recognize the number but picked up anyway. Steve from "Senior Benefits" - yep.. blocked. I'm in my 20s, no senior benefits needed.

They somehow managed to call AGAIN!

Of course. Even though you blocked the first number, they used a different number to call you back again with. Since you answered the phone,  they know they have a live body on the other end and most likely will call you again.

Called my landline on July 12th 2017 at 3:00 PM and CID displayed Phoenix AZ 602-553-3696 and since I don't know anybody who resides in Phoenix AZ or any other part of AZ, I let my answering machine take the call and as usual, no VM was left and since no VM was left, the call wasn't important to begin with.  I won't call the number back to find out why they called either. That's what the answering machine is for.  Just another scam in progress.
Caller: Phoenix AZ 602-553-3696
Call type: Nuisance call
