The best way to try and end the security contract that you have for five (5) years is to have a face to face meeting with the owner of the company to air the problems that you have had and see if the owner will agree to end the agreement in writing sooner rather than later.Mention the $150 charges you receive. If the owner refuses to end the contract sooner, refuse to pay the monthly amount and sue the security company in small claims court for the $150 fees you are assessed for the police coming as an example of the faulty system that is in place.
