Horrible first time experience!

So had my new alarm installed, advised them to come at 4. Called to confrim they would come at 4 to complete no one came back to me! At 10pm alarm starts goong off continuously for over a hour and a half. While in tears all control people are so horrifc towards me! Technical guys come on helps me turn it off poor security guy Sibusiso is here for an hour and no help from blue. What a first impression! What happens if a problen arises? How can i trust a conpany who cant help me after hours when their system is failing when their people who instal fail? I probably will get the standard messAge like everyone else! We as blue have heard your complaint and have responded during your incident like i have seen all over hello there peter! Blue is not customer centric at all!
