Shocking service, AGAIN, and exorbitant charges

After complaining of bad service twice in November, we once again had a shocking response from ADT on a callout, with their armed response team taking 80 minutes (!!!!) to respond to an alarm activation. After contacting ADT to complain, and very little in the way of apology, barring hollow platitudes, we decided to cancel due to their complete lack of acceptable response times. <br> They then proceeded to slap us with a ridiculous cancellation charge, which we refused to accept. Despite this, ADT have said they're charging us regardless. We complained again, and were told by Saadiqah Jacobs that the charge was non-negotiable. I then asked to speak to someone in management to take the complaint further, and no one has contacted me since. Utterly pathetic service from people who are supposed to be protecting our house. <br> I need someone who can actually attend to our concerns to contact me ASAP and listen to reason.
