    Your service tech Daniel came to our home to troubleshoot our system that had a failed communications issue. He was polite and respectful, and he competently restored our system’s second communication connection. He also helped change the batteries in some of our system’s detection devices like glass breaks and the like. We were pleased with the results of his efforts.

    Jessie and Sandra have been wonderful to work with! They are super responsive and very helpful in issuing work orders to a community I manage. If I could give more than 5 stars I would! Great job ladies! Your customer service is amazing!

    I have been a customer for 15 years. Safe systems bills 3 months in advance. I turned off my phone line in July but was paid up until October. I have asked for a refund for the months they provided no service and no they are sending me a past due notice for the next 3 months that they still can not provide service. I have had several phone calls, emails and snail mail interactions expressing they can not provide service. stop trying to intimidate me.

    My experience with Mike was very enjoyable and he was very clean and he helped me to understand what to do with the system. He works very nicely.
