ADT PATHETIC CUSTOMER RETENTIONS/CANCELLATIONS

DO NOT CHOOSE ADT!!! I have called up numerous times to cancel my services as I can no longer afford it due to the repo rate and there are also zones in my home that constantly need to be bypassed and in essence are not working properly. I was offered a possible decrease in premium and also that a technician would come out to me. Nobody called me back with a solution and I continued to be debited despite my cry out for help in that I am struggling to afford the instalment. I called up again a few times and was informed someone would call me but nobody did. Eventually on the 8th of December I called in and a gentleman informed me that it would never have been cancelled unless I sent an email. Each time I spoke with someone, I was never informed about this and just continued being debited. Eventually 29 December I call in once again and am given the following information: I am still in contract and they cannot guarantee a refund of my monies (no fault on my side as I requested to cancel numerous times and have just continued being ignored and they even have records of me calling up), if I was not available during 8 and 5 for the technician to come and fix I would need to be charged extra because they are coming to me outside of normal working hours(for something which they installed incorrectly and is not my fault at all). The services are pathetic and they are absolutely and completely non chalant about the customers wishes and struggles. They only worry about their own pockets and customer is not at the heart of their business. I would never recommend them to anyone. Even their response time is slow and there are hardly any of their vehicles patrolling the area when in other instances of other security companies, their cars are patrolling the entire day every day and they are much smaller companies.
