They keep calling me throughout the day and never leaving a voicemail to see who it is.

Fishing call rings only twice.  Tricky caller id with no area code, but text says "San Antonio."

This phone number is located in Westover Hills and is a 'call center'.  Their company is using a computer system to make robot-calls and when my answered it two days ago, a 'female' came on and asked if my wife would like to participate in a 'political survey'.
