I would send a registered letter to the elder body of the nearest KH and request no contact by mail or phone. Consider putting up a no trespassing sign after investigating the legal parameters in your area. If there is no mail receptacle or mail received at the KH, it might be fruitful to call the number listed about 10 minutes before a scheduled meeting and as for the elder in charge.
Be aware that the DNC slips in the territories are supposedly checked on by the elders once a year to see if they are up-to-date.
A note that the rank and file jw tends not to notice or listen to these notes in the territory cards. After all, making a mistake and calling on you just gives you another chance for "life."

When witnessing by telephone, what should we do if a person requests that Jehovah’s Witnesses not call again?The wishes of the person should be respected. A dated note with the name of the person should be placed in the territory envelope so that publishers will avoid calling that number in the future. Once a year, the list of people who have requested that we not call should be reviewed. Under the direction of the service overseer, experienced, tactful publishers can be assigned to contact these people to determine their current feelings.—See the June 1994 OurKingdomMinistry Question Box.

How should matters be handled when a householder insists that Jehovah’s Witnesses make no further calls at that home?
When we encounter a sign at the door that strictly prohibits calls of a religious nature and specifically mentions Jehovah’s Witnesses, it may be best to respect the householder’s wishes and avoid knocking.
Sometimes we come upon a sign prohibiting salesmen or solicitors. Since we are doing charitable religious work, that does not really apply to us. It would be appropriate to go ahead and knock at such doors. If the householder objects, we can tactfully explain why we feel that such signs do not apply in our case. If the householder then makes it clear that the prohibition includes Jehovah’s Witnesses, we will respect his wishes.
When we are working the territory, a householder may become visibly upset and emphatically insist that we do not call again. If he refuses to reason on the matter, we should comply with this request. A dated note should be placed in the territory envelope so that publishers working the territory in the future will avoid calling at that address.
Such homes are not to be avoided indefinitely. The present occupants may move away. We may contact another family member who will respond favorably. There is also the possibility that the householder to whom we spoke will have a change of heart and become more agreeable to having us call. So after some time a tactful inquiry should be made of the occupants to determine their current feelings.
The territory file should be reviewed once a year, making a list of the homes where we have been advised not to call. Under the direction of the service overseer, some tactful, experienced publishers can be assigned to visit these homes. It could be explained that we are calling to inquire if the same householder still lives there. The publisher should be familiar with the material in the Reasoning book, pages 15-24, entitled "How You Might Respond to Potential Conversation Stoppers." If there is a reasonable response, future calls can be made in the usual way. If the householder continues to be antagonistic, no further calls should be made until the following year. The local body of elders can decide if the circumstances in a particular case make it advisable to handle things differently.
