Septex Unlimited review: The system didn't work and all contact details were useless

The company Septex Unlimited installed the system and told to call if anything happened. I recently tried to contact them, but the phone number didn’t exist and all my emails were returned back. I have no idea why and how it has happened. But the company gave me wrong contact details and I didn’t check it. I’m very disappointed that I couldn’t get the services and their system was useless.
