ADT Security Shady Cancellation Policy, Internet

I have been an ADT Customer for 6 years.  I moved a year ago and thought I was just transferring my service from one place to another.  Little did I know, it renewed my contract for another 3 years.  Now I am moving and I will not... have an alarm at my new place.  ADT is charging me $932 to cancel my contract.  They did not install the equipment in this home, all they did is transfer the monitoring from my old home to this one. 

I was told when I transferred that it was a transfer of service.  When I called today I was told that I was locked into this contract and that this was explained to me when the technician came out to set my service up, which consisted of him making a few phone calls and collecting a check from me.  I promise, I will never use them again, I will see to it that no one I know ever uses them again.  The power of Social Media.  I will cost them far more than $932.
