I have been a customer with them for more than 20 years. I requested the installation of a doorbell camera and a complimentary upgrade for the control panel. When the technician arrived, I was informed that I needed to purchase an additional item for Google to ensure everything functioned properly. After the installation, my doorbell camera appeared poorly, as it was installed without a back piece, leading them to use caulking to fill the gaps in my front framework. Subsequently, it failed to work because it was dead, and they removed all the wiring, instructing me to charge it and rewire it once the job was done. However, they intended to charge me nearly $600 for the setup! For over 20 years, I have been on auto pay, yet they sent me a bill exceeding $700 because my bank declined to process a payment using a card from around 16 years ago. My bank investigated their charges after they unexpectedly changed my card number. They discovered that ADT had been imposing late fees on me every month despite my auto pay status. I contacted ADT customer service, and while I was explaining my situation, the male representative began to raise his voice, told me to be quiet, and insisted I should be professional and learn how to communicate, as he was going to inform me that they could do whatever they wanted according to the contract. I instructed him to cancel my ADT subscription immediately. Afterward, I attempted to log in to check the bizarre charges they were applying, but he had made me unauthorized to access my account. A few days later, I called again to confirm my cancellation and to discuss my bank's findings regarding the illegal late fee charges. After reviewing my file, this representative acknowledged that I had been charged late fees that I should not have incurred, but he offered to reverse the charges if I paid him $300. Today, I received yet another bill indicating that I owe nearly $1,000, and if I fail to pay, my services will be terminated. I canceled their services months ago!
