Bad service and no response to alarm

i installed ADT security system and i was informed that i should test the alarm once a month , and the very first day i tried the alarm the was no response cause no one called, and i was told it was fixed after calling but i tried testing it multiple times after with no response when i called the call centre and asked the lady to call me back they never did and i call again 2hours later with the concern for my family as i travel alot and dont like the uncer*****y of the alarm not working , then the i spoke to a lady called Shelly, who was completely useless and rude after talking to her with my own airtime for over 6minutes and i asked her to call me back as my airtime is finished and she asked me why? the system is still not working and the service is ****... im very disappointed with them and only to find out after 3months of having the system i found out the system is not working and their not getting any alerts on their side.

the quality of the service we were promised initially and the nonsense we have to endure are completely unacceptable, to think that a company that deals with the safety and security of people can be so useless and beyond my understanding.
