National Security Below Average Service

My Alarm tripped 3 times. I called the customer centre to find out why they did not call me to check if we where fine. I was told that they did call me and I agreed that all was fine. I had my cell phone with me and no one had ever called me. This is below average service and I fell that I am paying my subscription for nothing. I will be looking for better security companies as this is unacceptable service that will put myself and family at risk
