has called 3 times now and doesn't leave voice mail.

It was from a company in Augusta, GA doing a survey about your TV viewing habits.  It was pretty comprehensive, and I think the bottom line was that they were trying to find out if you would pay for a service that would store movies and TV shows that you paid for and wanted to watch on demand.  The service was called Ultraviolet.  I would not use such a service, but maybe younger people would.  I'd rather lay on the sofa and watch TV on a TV.

Taking a political survey about who I would vote for in the upcoming election.

I don't know this number and don't want them calling my phone

Much like the fella above, it was a survey about my TV viewing habits and what services and technology I had in my household. They were very polite and didn't ask too personal information. They asked about an advanced service offered through my cable internet company also.
