Called and didn't leave a message. If they don't leave a message, it's almost always spam.
As always, never answer the call, it will just make them call more often. Block the number if you can, and ignore it. These morons usually stop after a week or so.
The caller identified himself as Jordan Belford of Aetna. Same number: (289) 800-0303. Seems like he's middle eastern, Pakistani or India. Never tells you what he wants but tries to elicit information. Judging by the rest of the notes here, we'll just ignore him.
