I bought this service for my Mom. I bought the equipment outright so I do not need to return it. My Mom did not like using it because she kept forgetting to wear it and was embarrassed because the pendant was so big and obvious. I have been trying for over a year to cancel the service. They are charging me 185.79 a month. I've called to cancel a number of times, they said I had to send a cease and desist letter - which they then say they never received. Their website says to just call and request a cancellation, nothing about a cease and desist letter. Like others complaining about them, I had the same experience with my bank unable to help because it was an official valid purchase. Even if their product is the best on the market (not) their service and their billing abuse are not worth it. Stay Away!
