I installed their home monitoring system in my Florida home on March 15, 2012. Installation went great. I decided to have them install their system in my Ohio home in May/June, 2015. The 1st tech sent to do the installation had no clue how to install the system and what to do with the existing wired system. There were several issues, including multiple false alarms which led to having to pay a $50 line to local police. A supervisor was sent next - who didn't know how to fit it either. A 3rd tech was sent who solved the problems with the installation. I was told that I would be reimbursed for the $50 fine. That never happened. I continued to have problems with multiple 'low battery alerts' and finally had to schedule another tech to come fix that. I paid a $70 service fee to change one battery. With 6 months, the same battery was reporting 'low battery.' I continued having battery problems in Ohio and finally decided to switch to ADT in Dec. 2014. When their system was disconnected, no one called and the police dept. wasn't sent! I called 3 days later to inform them that their equipment had been removed. They told me I owed $339.11 for cancelling before my 3 year contract expired. I gave them my credit card to charge this amount to, and was given the information for how to dispute this charge. I immediately sent an email on Jan. 11, 2015 and provided all of the information that I was told to provide. I requested that they reimburse me for the $339.11, and that they provide me with an itemized statement that documented how they had arrived at this amount. No one contacted me until Sept. 29, 2015 stating that I had not paid the $339.11. Her name was Lupe. I gave her the exact date that this amount was charged to my credit card, and told her that I'd never received any response from my Jan. 11th email. She asked me to resend the email to her and promised that she would get back to me. She did call me back and left a voice mail with her direct phone extn. I called her back and left a message. She didn't call me back. Two months later, someone else called, again saying that I owed them the $339.11. Again, I explained everything, told him I'd talked to Lupe and she'd never returned my call. He worked in the same dept., and knew who Lupe was. He said he would talk to her and get back to me. That never happened. In my original letter, I informed them that I had installed their system in my FL home first - and there hadn't been any issues there - as I'd had in Ohio. If they wanted to keep me as a customer in FL, I encouraged them to consider my request for reimbursement. On Jan. 9, 2016, ADT installed their system in my FL home. Again, when Monitronic's system was disconnected and removed, no one called and the police weren't sent. I called Monitronics on Jan. 11 to inform then that their equipment had been removed and I was cancelling my contract. I was transferred to someone in their "Customer Loyalty Dept" to process my cancellation. Her name was Lucy. She told that Monitronics has no way of knowing that their equipment has been removed unless you contact them! I told her my whole story - including the $50 fine in Ohio that was never reimbursed. She told me that she would reimburse me that money and reduce my monthly monitoring fee if I stayed with them. Again, I told her that all of their equipment had been removed - and that I had received such poor customer service that I had no intention of staying with them. She said it would take them 30 days to disconnect my monitoring on their end, and I would have to pay additional monthly fees until 30 days after they received my cancellation letter. Then I would receive an invoice for the total amount owed for the cancellation. I sent my cancellation letter by certified mail. I stated that I was not paying their final invoice since they still owed me for the $50 police fine. As always, I received no acknowledgement of my letter and request. I received an invoice for $52.89. I received another invoice in February, that now added on a $5.00 late fee, which I have no intention of paying either. My customer number is [protected].
