"It appears this company engages in misleading sales tactics to trap customers into automatic yearly contract renewals. As many other Google reviewers have pointed out, they never clearly explain that the contract renews automatically each year. If you want to cancel, you're required to do so in writing, 30 days before the renewal dateâ otherwise, you're locked into another year of service. While we were remodeling our home, I tried to cancel the service by phone. However, Christian offered to pause the contract for six months, which seemed helpful at the time. In hindsight, itâ s clear this was just a tactic to keep us tied to the contract. Despite numerous conversations with Christian, he never once mentioned the critical details about how to properly cancel or the automatic renewal process. After over two years of not using the service, I called to officially cancel, only to be informed that I still had six months remaining on the contract. This lack of transparency and the constant hurdles to canceling the service are extremely frustrating. I would caution anyone considering this company to be aware of these practices."

"Hired Texas Connectivity to install my alarm and front door camera. For once, I didn?t have to wait to the tail end of my ?window of time?. Carlos [Provider Name Removed] communicated with me before and while he was on the way to come set everything up. He was professional throughout. He even talked to me about the process and the why?s behind the work. Totally appreciated the transparency. I?d definitely recommend Texas Connectivity and if it?s possible to ask for a certain representative - I?d also highly recommend Mr. [Provider Name Removed]. "

"For once we didn’t go with the “cheapest” option in the market. My spouse and I are always very budget conscious and typically go with the lowest price when buying something for our home. We realize this comes with pros and cons. While ADT was “middle of the road” in pricing, we feel that their experience, quality of products, and level of care are worth it. This has opened our eyes for future purchasing decisions. Thanks a bunch ADT."
