These jerks call me several times a week and this has been going on for years.  I never answer but finally I thought I'd try to get off their list.  As soon as I told a "representative" politely that I was not interested and to take me off their list, she hung up on me.  So much for being civil and polite.  I hope that karma catches up to those pieces of slime.  The sad thing is that I was put on hold for about five minutes before I could talk to one of these creeps so there must be lots of people falling for this crap.
