ADT non delivery of alarm

ADT were only too happy to accept a deposit of 50% for my requested alarm, but over a month since, I have yet to see my alarm or hear a word back from them.<br> <br> I have since complained numerous times, to no avail, and so have asked for a refund of my deposit at the appropriate email address: [Email Removed] But surprise, surprise no refund or even a reply 12 days since then, at time of writing.<br> <br> This is the worst service I can ever remember having. I am doubly surprised when such bad service comes from such a supposedly reputable company.<br> <br> Dear ADT, since you won't respond to me through your own complaint channels, perhaps I will have better luck complaining on a public forum like HelloPeter.
