I found how to get rid of this caller - American Institute for Cancer Research.  The calls are placed by InfoCision.  Contact the Better Business Bureau, Wise Gift Alliance Department, in Washington, D.C. (area code 202)  and file a complaint.  Explain in detail what is going on, including asking to be taken off the calling list and all telephone numbers used (I know of six).  The BBB will then contact AICR and in a week or so you will receive an e-mail telling you that your number has been removed from their calling list.  You might also want to read an article about them at http://www.bloomberg.com/news/2012-09-12/char ... lemarketer.html.
