However, this equipment had been installed only a 3 or 4 months prior, so I do not understand why ADT would have allowed this installation if they knew about this issue. Nobody has been able to explain why they moved forward with the installation, so my conclusion is that it resulted from ADT’s inability to communicate with their sales force and technicians keep in mind that the technician that came out to service garage door 1 wasn’t aware of this situation, while the technician that serviced garage door 2 DID know. After many hours spent trying to contact the right people within ADT to solve this problem, one of the customer service supervisors provided me with a statement credit and indicated that the manager at the local ADT office advised me to purchase a particular type of garage door opener at my own expense, which should then work with ADT equipment. When I attempted to directly contact this local office manager in order to determine the exact equipment model to purchase, I left three voicemails, none of which were returned. I exchanged an email with someone at ADT corporate, presumably about the frustrating situation, but when I inquired about HOW to get the local office manager to call me back, she also stopped responding I tried sending the email twice. When I tried calling the customer service supervisor who originally gave me a statement credit and advised me about the local office manager’s recommendation, that call also went unreturned.
