Appalling after sales service from Fidelity ADT!!

I had a Fidelity ADT security system installed in my home in July 2020. After a generally good sales and installation experience, that was as far as it went with Fidelity. I've requested remotes to go with the alarm system on 4 different occasions and to date have not received them. The last request was on Wednesday, 23 September where I was assured that I would finally receive the remotes and an appointment was made for Monday, 28 September with a technician. The technician never arrived. To date there has been no correspondence from Fidelity ADT to advise what happened or why the appointment was not honoured. Clearly all they care about at Fidelity is collecting monthly premiums, not the safety of their clients. I'm an extremely disappointed and disgruntled customer!!!
