This number has called at least 15 times in the past three weeks.  The only identification is "800 Service." I do not answer numbers I do not recognize, and I have invested in a call blocker, which hangs up after one ring on all 800 numbers and every other number I block.  It had changed my life and protected me against all of these scam ROBO calls which occur daily.  We have sadly lost the concept of a private phone and private number.

Started calling on 11/21/2013, 6:45 pm; 11/26, 5:30 pm; 12/03, 5:06 pm; 12/04, 8:08 pm; 12/18, 8:58 pm.

iOS7 allows you to block numbers.
