Useless service

adt installed a faulty alarm system in my place and now no one has showed up to fix it. Despite my attempts to call and email and leave messages on their website. <br> <br> As a result I have an alarm that's going off 24/7 and they are calling me a million times a day without being of any help.<br> <br> I would discourage anyone who is looking for a security company to choose ADT!!! And the issue stated above is not the only issue I have with them!
