They left a voicemail saying they were Premera Blue Cross calling with an important reminder.  It was an automated message, and left a tollfree call back number.

My parents are getting daily calls from 425 903 5434, giving them lectures about diabetes, which they don't have nor would they take health advice from an audio recording. This is harassment! Please get Premera Blue Cross to STOP THESE ROBO CALLS. They aren't even members of Blue Cross.
