If you don't want to speak to Jehovah's Witnesses, you can politely yet firmly request that they put you on their "do not call list". They should know what you are talking about. They may still come to your door to just make sure you want to stay on that list, but it should reduce the frequency of visits. You can also call the local Kingdom Hall and ask to be put on that list.
