If they continue to call after your request, you can take them to Small Claims Court for $1500 per call and report them to the FTC and FCC who can additionally fine them up to $16K per call. See if they have a Facebook page and post a complaint there as well.
this org. has called repeatedly after more than 10-15 requests to be removed. they do NOT respect the request and often get quite rude. I have to be suspect of them based on their tactics of 1. not respecting removal request, & 2. hateful, argumentative callers.
