This company(ies) are a ripoff. I signed up with security networks many years ago and tried to get the system cancelled after initial contract was over. Sent the letter and they said they never got cancellation letter. My contract was over. The company was then taken over by Monotronics and they sent me my contract which was over saying I still had a contract and they keep on billing me and calling me every day even more than once a day for payment. Now they are threatening me to turn over my account to collection agency. I hope this company gets shut down due to their dishonest practices.
