Sentry Security Systems Inc

Jeff Brennan is horrible to deal with. I left  several messages and spoke to him a couple of times. After I cancelled my service over a year ago. Some  how the alarm that was taken out of my house continues to fo off and the cops are dispatched to my house and I dont have the alarm. I am now contacting a attorney to look into the issue as to why he is not cancelling my service with central control What a headache

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.
