Didn't answer. Called back - said something along the lines of 'if you want to be placed on our do not call list and wish not to receive calls regarding....' I hung up there and just added them to my block caller list.
PLEASE DO NOT CALL THEM AND ASK TO BE REMOVED. That will simply increase the calls. This is some home protection service using an autodialer. I have been contacted by six different home protection companies so far. I ask them to take my number off their list - and I am sure they do this. They then pass my number to a different home protection services company. Six different companies in six different states have called so far - all offering home protection services.
