ADT FEDILITY SECURITY COMPANY

I am a loyal fidelity adt customer. I payed and installed the alarm system in my house last year. This year on the 20th of April I called Adt to report my alarm panel that is not working. They sent a technician on the 22nd of April. He came and found out that the panel was a problem which I already told the lady at the call center. Then the technician told us he will come back either on the 23 or 24 April. He didn't come,when I called again on the 26th I was told that I had to call again and book for a technician. Then another technician by the name of Michael was booked on the 27th of April on a public holiday .he came with a panel only to find out that the whole system needs to be replaced. He said he will come back on the 28th. He never came back then I called Adt again I was told that he's sick. I asked to speak to management but the call center agent never transferred me. He said they are aware they will send someone on the 29th. I called them again on the 29th of April to find out if there was a technician coming . An agent by the name of Charmaine who was rude told me that they booked me for the 7th of May. But they never communicated with me. I run a business from my home and I don't feel safe at all . Without their services that I'm paying for at the end of every month
