You could either file a restraining order or call the police and file a complaint against harassment from your landlord. If your lease is due to expire in over three months and the harassment is serious, you may be able to break the lease and move out quickly.
If it is your landlords' agents who are harassing you, consider reporting them to their professional body (if they are a member of one) such as ARLA. You could also consider contacting the landlord direct to complain as he may be unaware of his agent's conduct.
