Advanced Direct Security- ADT Authorized Company

I purchased an alarm systen and entered into a 3 year contract with ADT for my retirement property located in Holladay, TN in January 2013. This property is located approx. 517 miles from my primamry residence in Missouri. In January 2013 I began receiving "system error" alarms which the ADT sercice desk could not correct over the phone so they scheduled an ADT technician to come to my TN property in February 2014. The technician noted the emergency light/siren components of my alarm system were not wired AC with DC back-up as required and was powered solely by battery and the battery was dead. The tech ordered a replacement battery which took two days to arrive and for which I had to schedule another maintenance appointment. The tech told me the battery would only last a year and I would have to schedule it to be replaced every year in January. I told him this was unacceptable as I requested and was paying for an AC powered system with battery back-up because my property was located in a remote area off the main road and the only way the police would be able to find it was by locating the light/siren. The tech told me to contact ADT which I did through my on-line "My ADT" account. I filed an official compliant with ADT concerning this issue in March 2014 via their on-line customer service. To date I have never received a response to this written complaint. I was visiting my property again in May 2014 (I usually only visit the property two or three times a year, but this year I made additional trips because we were moving some valuable items in the building located there - which is why we have it alarmed). In May 2014 I notied another "system error" message and called the ADT service desk. They scheduled another tehcnician to come to my property June 5, 2014 to repair the malfunctioning light/siren. The technician could not fix the light/siren so he told me he was going to order a new light/siren and this one would be AC powered with battery back-up as required. He also indciated that ADT sometimes subcontracted projects and apparently a subcontractor installed my original light/siren as the equipment was "non-standard". The ADT service desk contcated me on June 9, 2014 and attempted to schedule the equipment replacement appointment for June 16th. I told them I could not be there that day as I had to drive 517 miles one way from my MO residence. I asked if the appointment could be scheduled for the afternoon of July 3, 2014 as we intended to be in TN for the 4th of July weekend. The service desk rep said this would be fine and scheduled me for 12 - 5 PM, July 3, 2014. I received a "reminder email" from ADT on July 2, 2014 reminding me of my July 3rd, 12 - 5 PM appointment. I worked July 2nd and then got up at 1 AM July 3rd in order to drive to my TN property to meet the ADT technician between 12 - 5 PM. I arrived at approx. 1045 AM July 3rd and received a voice mail from ADT at approx.1145 informing me my 12 - 5 PM appointment was canceled because the parts to my system did not come in and were not projected to be available until July 9, 2014 and that my appointment would have to be rescheduled!!! I was of course furious and immediately attempted to call the ADT service desk at the 1-800 number they left and I was put on hold "due to an unsually high volume of calls" for approx. 45 minutes until the battery on my cell phone died. To add insult to injury I received another voice mail from the ADT service desk at approx. 830 AM July 5, 2014 infroming me that the parts to my alarm system "miraculously" (my word) came in and to please give them a call at their 1-800 number and the technician would come out that day to install the part. I attempted to call the ADT 1-800 number provided 3 times that morning and each time I was placed on hold yet again "due to an unusually high volume of calls" for anywhere from 20 to 40 minutes each time. I was only able to speak to a human being once and after I explained the situation she was going to transfer me to "the correct department" and when she did of course the connection was cut! I mentioned my property is located in a remote area and the cell phone service is spotty at best and the phone signal is very weak, plus there are no telephone or internet lines/service to this property. I returned to my MO residence on July 6th and immediately filed another written compliant to ADT through the "My ADT" on-line system and in this compliant I asked for a "senior manager to contact me immediately concerning this issue". On July 8, 2014 the ADT service desk called me in an attempt to schedule another appointment to have my equipment repaired. I told the service desk representative I could not schedule an appointment now because the property was located 517 miles from my residence and that I filed an official complaint with ADT over this issue and was waiting to be contacted by a senior manager. The service desk rep stated she would alo oforward my complaint to her manager. On July 11, 2014 I received an email from a Thomas Le Gard, ADT Corporate Customer Service Rep and he provided a phone number to contact him. I immediately called him on July 11th at the number provided and was sent straight to his voice mail. I left him a voice mail and asked him to contact me at either my home phone or cell phone and provided those numbers. I also sent him a written complaint via email outlining the issue. I recieved no reply from him and on July 16th I emailed him again. He apologized for not contacting me because he "suddenly fell ill and was not at work." He promised to have a senior manager contact me within 24 hours and to date (July 30, 2014) no one from ADT has contacted me concerning this issue. NOTE: The ADT technician in TN who originally cancelled the July 3rd appointment (I believe fraudently so he could go on 4th of July holiday early) has called me directly several times at my home to reschedule the appointment he cancelled, but I refuse to take his calls and will only speak to someone in authority at ADT. The bottom-line is my alarm system system, which I paid $1400 for and am making $45.42 monthly payments is defective and customer service at ADT is "non-existent"!!
