Calls several times a day, never leaves a message.  I dont pick up at all.

Left a pre-recorded message about life insurance. No call back number (not that I would) or company name.

I didn't pick up. No voicemail left.

Robo-call about life insurance for people over 50 - no one in my household is that old.

We got a call from this number today at 1:49 pm and didn't answer. The caller ID was AMHERST MA. No voicemail message was left. When I called back (our number is hidden by default on outgoing calls) I heard a recording of a woman's voice which said "We're sorry. The number you're trying to reach is no longer in service." The number will be added to our call blocker. I highly recommend such a device to avoid these nuisances.
