Failure to provide the service

On Saturday, 2021/12/04, at about 03:00, my house was broken into while i was inside sleeping. Before i slept i activated the alarm but the intruders managed to force open the window and forcefully broke the burglar and entered the into the lounge. Amazingly the detector was facing the window they used to enter. They removed the mounted Television from the wall, a 55 inch tv. Only when they exited the house the alarm went on, i woke up due to the alarm but it was late. National Security only send a technician on Monday to assess and check if their alarm system was working. These happened only 3 months after they installed this system. I sent several emails to them to give me a way forward since their alarm system failed to deter or prevent any intrusion into my house and they never came back to me. Their system failed not me. Now what is the reason to have a system that does not serve the purpose yet they made us to sign a three years contract, if they failed me in three month how are they going to protect my household in three years.
