NO Response from ADT Head Office

I had a new alarm installed, I then had issues with it months down the line, since the tech has been out, I happened to check the alarm a couple of weeks ago and the main passives are not working. Which means for the last couple of months, the house has not had an alarm, but I have been paying. <br> I demand a credit and or a technician to be sent immediatly at no charge to correct this. <br> <br>
