ADVICE: DON'T ANSWER!!! SO many calls from these people every day! My husband once took their "BRIEF"  survey hoping they wouldn't call anymore, and now they call NON STOP! They talk over you if you ask questions that don't fit their agenda, (if they don't hang up on you first), actually argue and talk over you, are unwilling to transfer to any sort of "management", etc. I've asked many times to be removed from their list which clearly hasn't worked.
