Update...

I was able to get out of the deal because i was careful when i signed up and kept my paperwork. I knew that I did not extend my contract but the ADT "customer service people" kept arguing with me that I did. I was able to find the contract that I signed. It did show that the the contract was a new 36mo deal but the installer wrote the total cost as the amount that 1 year of payments should be. He then wrote a rider that changed the terms to 1 year.

When I called ADT back with this new info, they told me that I was wrong. When I sent them the contract with the total amount paid, I said "just keep the alarm active and quit charging me, I paid you the terms agreed to and your contract has no penalty for pre-payment". They then told me that as long as the alarm was active, they would charge me.

Finally took talking to a VP, who saw the paperwork, apologized profusely, and got it all worked out. He then said he had to go ruin the day of some people that used to work in customer service. I dont know what happened, and i dont care. Just glad to be done with them.
