Terrible security company which I have tolerated for far too long.

I have been a customer of Fidelity ADT for 20 years, but I soon won't be any longer. For about a month they have been sending me two or even three SMS messages daily, telling me to test my alarm. I am well aware that one needs to do this monthly, but this is now bordering on harrassment- AND I have had their technician at the property only last week to replace a faulty beam sensor, so the alarm has been tested very recently. When I phoned the call centre today, I spoke to a very apathetic man who basically told me that I must be mistaken, my alarm must be faulty or I have to inform ADT in writing if I don't want the SMSes. Their call centre is generally awful anyway, and they can never seem to retain instructions concerning change of contact details etc when we have house-sitters. So as soon as I have the time, I intend to terminate their services and move to a different security company. I would definitely not recommend them.
