Unlike most legitimate companies, atd does not allow you to cancel your alarm services via their user account system and they require you to send a written and signed request for cancellation. They give no confirmation of receipt of my cancellation fax. So i e-mailed them and received confirmation that my account was closed. Even then, they continue to do the automatic payment withdrawals from my account. The next e-mail said my account was not cancelled and i needed to give written and signed 30 day notice again. I cancelled my account in writing via fax on 10/20/2015 and just had a $50 withdrawal from my bank account on 12/14/2015 from adt. Lesson learned - never use adt for your security needs and if you do, don't give them your account information to do automatic bill pay. They are a scamming the people they are supposed to be protecting!
