We started using ADT burglar alarm service at October 2009. After a year we decided to move out from the premises and called ADT to cancel the service. They told us the contract was for 5 years. After checking the contract we saw the 'five' years term in the small print part of the contract. (Not in numerical form but the word 'five' instead). Our sales representative Gregori Krakobski assured us that the deal did not include any commitments etc... As you may guess, he simply lied and misled us. I think ADT allows (or maybe promotes) this kind of scam done by their sales reps because they are not helpful on the phone and even if you try to contact to Corporate Customer Relations Consultants in Florida. As a result, we were not aware of a 5 year contract and the signing was like a bait-and-switch deal. After experiencing this with ADT, I personally persuaded the company I work to switch their alarm systems in 3 different locations to other security company (which offered significant discounts though, and free setup). Everything fine for now but ADT problem still not solved. Interestingly the early termination fee they want us to pay is the sum of remaining 4 years.
