If you have something on your property that has no right to be there, then the final step is to notify them in writing, by recorded delivery, of your intention to:

1. Remove and dispose of the items in 28 days from the date of the letter;
2. Make good the damage caused by the original installation and
3. Make a claim in the Small Claims Court to recover your reasonable costs arising from the above.

If you think you've hit a brick wall, now is as good a time as any to do this.
