SENTRY SECURITY SYSTEMS INC

Jeff, the owner, came out the next day, but only after I told him how serious this was and that our fire company said we could have died from the carbon monoxide in the house. Jeff said he wasn't sure why the alarm didn't go off (we had high CO levels in basement where alarm was located). Said he'd get us a replacement the following Monday (3 days away). He never showed up, didn't return 4 voicemail messages we left, and we never heard from him again. Extremely unprofessional, poor customer service even during an emergency situation. Unresponsive.

Jeff is incredibly unprofessional and unethical. He was late or noshowed every appointment he scheduled to perform the work always claiming some personal issue. What should have been done in a few days dragged out for weeks and weeks. He "installed" a subpar wifi extender that I could have purchased at Best Buy for half the cost and when I complained that it didn't improve our service he kept telling me that it was our internet providers fault. After paying them several times to come out we finally hired another company to fix his work. Our alarm system went offline and he refused to reset it. We prepaid for a ful year and still have 6 mo this left on our contract and will not return calls or texts. Don't ever do business with someone that would put you in the position where you are unable to protect your family

Jeffrey Brennan from Sentry Security Systems Inc., in Havertown, Pennsylvania is not to be trusted. He kept my cash deposit of $4000, and did not follow through with our previously agreed upon contract. When I won a judgment against him for not following through with the contract, he wrote a check from his Federal Credit Union in front of Judge Elisa C. Lacianca, it bounced, and I collected nothing. You work too hard for your money to be conned by this unscrupulous individual.
