I called to cancel my service. I am currently on a month to month, and have had Monitronics service for last 10 years! I was told that they are gonna wait another 30 days to cancel the service after they get it in writing. This is just a way to extract more money from people and is really like a SCAM. Do not go with Monitronics, this is how they approach things after 10 years of customer relationship.
