Don't trust Medical Alert! I set up the rental of this equipment for my mother. We paid one full year in advance. She was then billed another $30 3 months into service. I canceled then returned the equipment and called them. Then they are taking 5 weeks to return unused funds. I wish I didn't have to give them a whole star. The first time I called to get the money returned the lady would not listen to me at all. I had to get angry and call back before I could get someone with any brains; the first lady I was talking to kept talking over me making up some big lies about some agreements that we never signed. Don't go there!
