From reading the thread below, it looks like this is just as I suspected...another scam/troll.  So annoying when you're dealing with limited minutes on a government cell phone that has no way of blocking anyone.

I didn't answer, left no voicemail. Sounds like another scam call. Oddly enough I have received 3 in the last 24 hours. I wonder if lots of people are seeing an uptick in these kind of calls.

Half a ring then hung up.  Then again one minute later.  No message.

Received unwanted call from 516-246-7113 at 230pm

It was a rewards redemption number...joke
