You don't get feedback or respond from ADT

I have struggled since May 2014 for ADT to sort out my account! I am in fact in advance, but nobody care to sort it out, it does not even help to report the complaint on their website, maybe that is why the staff are also not worried! After complaining on the website they send a automated respond mail that I will be contacted with in 24 hours. I received this mail on the 23rd February 2016, it is now 8 days later??!! To get hold of the CEO is just as difficult seems he is on a throne? I have heard many people complaining about ADT, they even at one stage stopped my security service. Can't wait for my contract period to end, showing a account that is in arrears, because then we can take the matter further in court!
