D M Barry Security Systems

I have been trying to get service for my alarm system and he does not return my call. My system keeps alarming and waking me up. I have not had a contract with him through [redacted] for a year and a half, yet when my alarm went off recently, I realized he never cancelled the monitoring system when I did not renew the contract. When I called [redacted] (###-###-####) they said I could not shut this off unless they got a letter from. DM Barry Security (###-###-####) I cannot get service for my Ademco Honeywell System because he does not call back for service. Therefore I cannot sleep at night when I arm the system because there is something wrong and the siren goes off in the middle of the night. I then get a call from [redacted] that I never renewed the contract with DM Barry. Meanwhile I feel unsafe when it's not armed at night. PLEASE HELP ME GET OUT OF THIS MESS SO I CAN SIGN UP WITH A REPUTABLE COMPANY!! Thank you very much!!
