Called my phone. I didn't recognize the number, so I didn't answer it. They left a voicemail, but it was just a recording saying I could claim blah blah blah. I deleted the voicemail and blocked the number.

It's legit. An automated (but responsive to voice replies) message regarding prescription coverage for a worker's comp claim filed by someone in our household. They wanted to let us know that a card was on the way and what to do if we needed a prescription before it arrived.

This is a legit automated call informing me of my workman's comp claim.

Four calls today. My voicemail does not work
Do not want them to call at all.

Yes it might be legit, but they called the office and it was an automated message asking if the party was available.  But they weren't here in the office, so attempt to get a call back number (is not the same # as the number they called from) resulted in the message cutting out before the last set of numbers.  SO legit or not - I can't even pass the information along!  Nice job.
