Poor service.

<p>I had been a client of ADT since 2001. I owned the alarm system, and only made use of the monitoring and the armed response service. In mid 2015 I lost my job, and because I could no longer afford the premiums, I faxed ADT a cancellation letter giving the required 30 day notice period. The fax was sent from a post net depot and the confirmation was that it was sent successfully. That was the beginning of November 2015. </p> <p> </p> <p>I received no correspondence from ADT until, November 2016 via an SMS saying I needed to contact ADT, re: bad debt. </p> <p>I contacted the number and was put on hold for about 20 minutes because the consultant could not find my file or any records of me on their system. The next day I received a call from ADT saying I owe them outstanding premiums from August 2015 to May 2016. I informed the consultant that I had sent through a cancellation letter, to which she rep**** they never received it, and that I was liable for the outstanding balance. I refused as I had followed the correct procedure to cancel the service. In January 2017 I received a call from ADT threatening to blacklist me for non payment. The consultant also said they had been sending me correspondence to an email address that I had stopped using in 2010. I have a contract filled in by an ADT consultant after that date with my updated details.</p> <p> </p> <p>How can I be liable for services that I had cancelled and furthermore I did not receive and service from ADT when my alarm was triggered at my premises after the date of me sending the cancellation letter. </p> <p> </p> <p>Absolutely shocking service!!!</p> <p> </p>
