I have also learned the hard way!. I cancelled my service with ADT on the 9th March 2011 and specifically asked the accounts department whether i will be billed again in April as i was leaving the premises end of March and was told i would NOT be billed again, lo and behold on the 2 of April i was debited once again!. After being pushed from pillar to post and ending up with a Jaques who sweetly told me it is a calender month that's why it went off, after venting my spleen somewhat on him and in no way being personal towwards him he put the phone down on me. If he still corrected me or asked me to remian calm i would not have gone on a campaign such as this but i only recently found out from one of their salespeople(Warren) that i was actually entitled to 1(0ne) years free response as my wife had passed away and the contract was originally signed in her name. Nice, once again no one communicates with the client but rather let it slip though and let the customer pay religiously every month. Shame on you ADT i am so glad the CPA has come into effect, this will hopefully take care of scoundrels such as yourselves in the long run! This is the exact same complaint that i placed on Hellopeter.com, i believe the public must be informed of companies such as these and not just willingly put their signatures to paper by believing everything that is explained to them by the respective salesperson. Shop around and get other companies to give you quotes on security, the figures speak for themselves as there is daily valid complaints about this particular company.
