Fidelity ADT worst service imaginable

My home alarm had been giving problems since 30 Nov 2019. On 02 Dec 2019 I reported the fault and a booking was made for 03 Dec 2019. I received an sms with this confirmation. Then, after sitting at home the whole day, waiting for the technical dept, no one pitched, not even a call saying they will not make it. Then, after many fights & being promised a technician will come out on 09 Dec 2019 around 17:00, by 20:00, no one arrived. After numerous calls, a guy eventually arrived around 22:30. He could not get away quick enough and guys what, 2 days later the same issue again. Then the night of 11 to 12 Dec 2019, my home alarm kept going off the whole night, so much so that I eventually around 01:30 totally disarmed it. After lots if calls on 12 Dec 2019, it was arranged that a technician will come to my house at 17:00. They did arrive, only to tell me there is an fault on my lounge PIR, by they do not have equipment for repairs. I then spoke to their technical manager, a person by the name of Galafani. He was to say the least, rude. Just saying that is now the situation and that I'll have to wait until 17 Dec 2019 for them to come and replace it. How is it, that I report a fault, the technician arrive without equipment for repairs? How is it that clients, who pay for a service is treated like **** and that they are actually doing you a favour? How is it that there is never a manager available to speak to? How is it that a customer, after battling for 2 weeks, who is paying for a service, gets treated like this? ADT to really come and remove their useless system from my house.
