Beware and do not trust ADT with your financial information of any kind (sad that you trust your home in their hand because of a contract that you they will not let you off hook!).
As I was paying them on line, they helped themselves to charge my credit card which was supposed to be "on file only" too. When I stopped that and asked for my money back, they turned me in to a collection agency. When I contacted them, they apologized, I paid the balance using my check book on the phone and I was out of collection. Now that they have my checking account information, they are charging my bank account without authorization!!!
Short of taking them to the courts, what are my options? I don't TRUST them to have access to my home!
