Gisele at the Blue Shield Elderly Independence Division truly deserves a glowing commendation for…read moreher remarkable professionalism and compassion. Her assistance in choosing a 24/7 fall‑detection watch for my 98‑year‑old father with dementia was exceptional in every way. Gisele devoted a full 2hours to carefully walking me through every feature and service option. She clearly explained that the watch continuously monitors for hard falls and sends instant alerts, even if my father cannot reach a phone, and that it operates reliably day and night to provide constant protection. She also emphasized that emergency notifications go directly to family members so there is no delay or uncertainty when something goes wrong. Gisele aslo thoroughly demonstrated the GPS location tracking and heart‑rate monitoring, which are absolutely critical for my father, who can wander and is unable to reliably state where he is. Knowing we can see his real‑time location, monitor his heart rate, and that he can contact his children or 911 in an emergency gives our entire family tremendous peace of mind. Gisele repeatedly reassured me that this system is designed to safeguard him and keep us fully informed. What impressed me most was Gisele's warmth and empathy. She never rushed the conversation, answered every question in plain languageI could understand, and always spoke about my father with deep respect. She transformed what had been a stressful and emotional decision into one that now feels confident and secure. Because of Gisele's dedication, I am convinced my father is far better protected, and our family can finally rest easier knowing we have the right watch and support in place.

The day came and nothing, so I called 2 hours after the said time and oops she scheduled the wrong date. Mind you, no apologies. So 2nd time around.. NOTHING. No Call or No Show. So of course, I called again and again and again and got the voicemail. Left several messages return my call and reschedule us for the following week. NOTHING again. IF YOUR SHORT STAFFED, HAVE THE DECENCY TO LET YOUR CUSTOMER'S KNOW BY RETURNING THIER CALLS. IT DOES NOT TAKE 2 DAYS TO RETURN A MESSAGE. Your customer service is disappointing. COMMUNICATION IS KEY!

Or worse, the alarm goes off for no reason & we have to constantly press the "alarm acknowledge" button to shut it up! We've had several "techs" come out to check it at $110/hr. with a minimum of 2 hours. They still can't give us a good reason as to why it doesn't work the way it should. Their recommendation? Replacing the whole system. What the what?!! Replace the whole system that we bought less than a year ago & spent tons of money on?!!! When we do replace the system, it will most definitely not be with National!

Not to take away from the hard-working employees at Aloha Alarm, but the account manager "C" really…read moresucks!!...I've been trying to stop my alarm service since December, since we're moving. No response, left multiple messages with customer service, spoke to a rep 2 days ago in the service dept, always the same answer, "C" is not in today, but when she comes in she'll call you back, and we'll also let another manager "J" know as well. Meaningless dribble...no calls after leaving multiple messages from anyone. Something tells me something is "going on" (management issues, financial issues, etc.) at that company, and not in a good way. When they don't respond to customers and in effect leave decision making to one person, who chooses to either not show up to work or is too "busy" to even return calls to customers, something is definitely wrong. Maybe they need to replace her or the entire management. Customers are not being serviced properly. Next step for me is to reach out to the State DCCA to file a complaint. If you feel you're not being treated fairly I suggest you do the same. Some action has to be taken to wake these people up or else it will remain the same. Me, I'm outta here with these guys, we had service for years but seems current management is sub-par and not taking care of customers. Watch for more reviews, if the negative trend continues, it's telling you something is really going on. Good Luck in the New Year!
