Bad service at ADT FEDELITY

The worst experience I have ever encounter with any service provider.I had a problem with my alarm system my panic button didnt work so I called Adt and let them know .THEY SAID TO ME THAT THEY WILL SEND A TECHNICIAN THAT I MUST PAY,WHICH I QUESTIONED BECAUSE THEIR SYSTEM WAS IN FAULT .SO I SAID ITS FINE I AM CANCELLING MY SUBSCRIPTION WITH THEM AND I GOT A CALL A DAY LATER FROM SOMEONE CLAIMING TO BE THE MANAGER OF THE CONSULTANT THAT WAS DEALING WITH MY CASE AND HE APOLOGISED AND SAID THE CONSULTANT GAVE ME WRONG INFORMATION I WILL NOT BE CHARGED FOR THIS TECHNICIAN THAT WAS ON THE 10th february 2020 and I made the call on the 7th februsry.he said the technicial will come on the 12th of February between 12-3pm so I took half day at work to get there on time for the Technician,guess whet he never came and this is the second time they doing this to me they did this in january as well and I called them and they dont even care I was put on hold for 15 minutes to be directed to the consultant who was handling my case .These people are so unprofessional and ***********.
