My alarm system malfunctions sometimes. The last time I could not turn it off. It beeped all day and night. Want to cancel the service, but they would not do it unless I paid $500. Said I had a phone contract. We never made a phone contract. I have been trying to cancel the service for a couple of years. I am 96 years old and don't know how long I will be in this house. They said I have 22 months to go. I will be 98 by the time this contract ends. I am afraid they will enact another so-called phone contract without calling me. User's recommendation: Use another company.
