The customer service representatives are absolutely terrible. They are unprofessional and incompetent. I've been a customer for 3 years and the two times that I've called for assistance I have waited on hold for almost an hour for the rep to be completely unhelpful, incompetent, rude and unprofessional. Both times my calls were miraculously ended without a returned call from ADT. Needless to say, my issue has not been resolved and I will need to spend additional time on hold in hopes to speak with someone who can actually assist. I am saddened I extended my contract but it was prior to having these experiences and disappointed I will have to continue with such an incompetent company until my contract is complete.
