I received bad service and breach of contract, after several times calling and complaining with no assistance i tghen cancelled my contract which is still n ot as i still received invoices to pay for no service provided

below is the letter I sent to ADT Bloemfontein in September 2016 and again December 2016 but still I continued to receive invoice for bad/no service. to explain shortly, this started in December 2015 whereby the alarm go off and we know when it happens I will get a phone call and or the patrol officer will come out, I didn't see that happening. I also knew every December time ADT will call me to arrange that there's someone at home for testing the systems that didn't happen in December 2015. that's when I called to report it as it happen for several times that alarm goes off and not get a call. I was promised that technical person from ADT will come test but to no avail. I then saw the patrol officer in the street and call him to relate the problem to him who then advised me to call the office, I told him I already did but I still called again still no one came. I still received invoices and calls to pay my account and related my same problem to the caller who then gave me the email address to send my cancellation letter. I send the letter three times but the account wasn't cancelled as they continued sending invoices and calls. I then stopped the debit order with my bank. I spoke to a lady at ADT by the name of Viola Mdluli on the 02 November 2017 and related this and sent her the cancelations I sent previously and told her am not liable for that and I already never received service I had break ins three times the last one they stole a flat screen TV in the house, dismantled that alarm system and was put on my bed because it was ringing though ADT did not attend to it because apparently it didn't ring to wherever it supposed to since December 2015. Viola I thought she will help but now she's not. now my big problem is that they took my name and account to credit worx debt collectors. which is so uncalled for and am so angry as hell.

"I would like to terminate my contract as the service was already terminated by you, with immediate effect. I have already complained for several times previously that I did never received a service from you since December 2015. Then when I saw one of your patrol staff by the name of Thekisho his surname I told him that when the alarm goes off I expected a call and or somebody to come but that did not happen, he advised me to call the office to report so it can be tested. I called then for few times and was promised somebody will come out to check and test but that never happened. That went on for several months with no help. I even went on holiday in December/January which was so difficult for me under those circumstances but had to talk to my brother who’s a police officer to patrol my house knowing that the alarm will still go off and will not be attended to. Later in the year I instructed my bank to reject the debit order as am paying but not getting the service as supposed to. Since then am not paying because since then the alarm is still going off and still no phone call and no one coming to check. I will not and will never pay for something that I’m not getting any benefit and or any service. To my surprise only yesterday when the alarm went off the guy from ADT came to check, I was like what?? Was really surprised. What should happen now is that I would like to terminate this contract as the service was already terminated and again I do not trust you anymore. What happened also is that my 3 new dresses disappeared from the line somewhere in October November after which I was never attended to. I do not want to point fingers but knowing that before then this has never happened as we would leave washing on the line for the whole night and nothing would happen. And this time my dresses were even hang on the line next to my sliding door, no ***** from the street would have gone that far. Few months after that it’s not happening again, I leave washing on the line again and nothing is happening. Without taking anything from this, prior 2015 November all was good and the service when it lasted."
