Got the same call tonight from a 317 area code.
Whenever I get these calls on my cell phone, I just move them into auto reject list.
Also always have to remind my parents, nice but too trustful for these days, not to give out any personal or financial info to anyone over the phone no matter whom they are claiming to be.
The problem is, you're blocking someone else. They typically spoof the number and keep changing them.
I just got called, and my co-worker got called less than 5 minutes later from the same guy.
They have a poorly assembled website (replete with Lorem Ipsum), but there's nothing else on the web about them, except I have a suspicion that they're a rebranded "National Police Support Fund".
There's nothing to make me believe these guy(s) are at all legit.
