ADT is truly the best

Where do I start?!! ADT is truly the best!! I had the pleasure of speaking with Tori today! She was excellent, professional and truly went above and beyond in her kind, compassionate care and commitment to providing me with the best service possible. I was in such a time crunch, but I was able to call, order the test, pay for it over the phone and get the test I needed within the hour. Not only did this put my mind at ease, they saved my job!! I am forever grateful for this team of hard workers, that care, with such great work ethics! Thank you from the very bottom of my heart!!! If you need a drug, alcohol, etc… screening, this team will be your lifesavers!!
