ADT No response

After receiving no response to upgrade my alarm system, I switched suppliers. Then gave written cancellation of my armed response in October via ADT process, again no response. Raised through hellopeter and ADT head office then started receiving delayed response. I was debited for 2016 annual fees end of November a month after cancelling for the year upcoming. I called ADT accounts who promised to resolve, still no response. Ive asked ADT to collect their radio pad, no response. My last ADT complaint they couldnt find my contact details, this is the company entrusted to protect my family (and yours) who cant even follow basic process or respond to emails or telephone calls. Please anyone signing try Beagle Watch or Chubb, ADT doesnt respond to emails or even alarm activations (check my HelloPeter complaint from early 2015 where ADT took over an hour to get to a distress alarm).
