Faulty Product

This is now the 4th time I am complaining about the ADT unit that has been installed at our premises. A tech came out last week Thursday to check the system which suddenly started working. From yesterday the system light came on. I pressed #2 and 1 was highlighted which refers to the battery being faulty. <br> <br> Whats the point of paying a faulty unit which you can not arm? Where is the safety in that?<br> <br> We are giving ADT one final chance to sort out all issues or we want the unit removed and we will move to another security company who can provide us with better service!
