Restraining Order
It might be the time to get a restraining order to stop the harassment. Consult with an attorney about what’s best moving forward. There are attorneys that specialize with working with those affected by harassment and stalking.
The Last Resort
If you’ve exhausted all other options, it might be time to consider filing a civil lawsuit. This is especially true if you’ve experienced any losses due to their harassment. You could also get compensated for any pain or suffering you’ve experienced in general.
