Failure to deliver as per verbal agreement.

On the 12/01/2015 an ADT technician came to my house to do a routine inspection of my alarm system, upon which it was discovered that one of the motion sensors are not in working order. The technician then promptly agreed to send an email as soon as he was back at the office in order to create awareness of the problem, and assured me that someone would come over to repair the broken motion sensor as soon as possible. It has been nearly a week and I have received no feedback from ADT regarding this matter, even after I had sent numerous emails, one of which was to the head office. This is utterly unacceptable and leaves my family and I feeling vulnerable and unsafe.
