We've been customers since 2014. The initial alarm and sensor install and service was excellent, with friendly helpful service, and good advice. The prices were all reasonable. Over the years, service has waned. We have had several false alarms where we did not get follow-up calls from the monitoring service. When we've called with questions, it is rare to get a returned call. We have spent the last 6 months trying to change our credit card for monthly payments, and have not yet succeeded. They either don't call back, or take a message but don't take any action.
