We attained the services of ADT. 1 month later our home was broken into. The system failed to protect us. We chose ADT because of the rebate they offered; pay $300 installation fee and get $200 back within 4 to 6 weeks. Never ever got the check after multiple complaints. They have another gurantee that states ; If you are not happy within 6 months of ADT services we will refund all monotoring fees and installation. Adt will not honor that gurantee either. The other gurantee states: ADT will reimburse you up to $500 in the event of bulgary. Its all a bunch of lies just to get you to sign their 3 year contract. My mother attained their services as well. It has been 6 months and still no rebate check. They are a bunch of crooks I honestly have to question the honesty of their employees as well. I would not be surprised if the police told me that the fingerprints lead back to an ADT employee. Go elseware they will not honor any of their gurantees and the honesty of their employee is questionable.
