ADT can't provide good service, yet won't cancel

I joined ADT in January 2018 for my business.

Immediately on installation we had problems, as the incorrect size hard drive was installed, no dome cameras (quoted for) were installed, and the recording device was not accessible via the internet which was a requirement from the start. After a series of phone calls, e-mails, and complaints, these were all remedied circa February 2018.

Shortly after this our alarm started going off. We were told the door sensor was faulty, even though it should still have been under warranty we paid R504.27 in October 2018 to have this "fixed". It did not solve the problem, the alarm continued to go off and we were threatened with extra call out fees. After repeated callouts and complaining, we were again charged R1003.95 in April 2019 for a new battery and another door sensor. Again the problem was not solved and our alarm continued to go off. All this at huge inconvenience to us, as we had to go out and disarm the alarm each time. Between October 2018 and April 2019 we had to disarm our alarm several weeks at a time and repeatedly complained to the dispatcher that we were sick of paying for no result. She just said she would pass the message on but we would never hear from ADT. Eventually, after spending all this extra money, having the huge inconvenience of having to get out of bed at all strange hours of the morning, and the frustration of having technicians repeatedly come to investigate to either find nothing or "fix" it only to have it go off again, we decided to cancel. Obviously ADT cannot provide us with the service we signed up for, and we cannot keep paying to have the alarm "fixed".

We informed ADT in June 2019 to cancel with immediate effect. Their response was to threaten us with cancellation fees. I told them since they kept making me pay to "fix" the problem and we've had problems since the start, I am not willing to pay this. I reconfirmed that I want to cancel to Rassie Erasmus on 20 June 2019. No response and in July I was simply debited again.

I want nothing further to do with your company. You have provided me with bad service and cannot provide with advice for how to fix the alarm yet expect me to just cough up for non-working solutions each time with no refund. I am not willing to pay cancellation fees, and I will not allow my account to be debited again. Please cancel this contract with immediate affect, and collect whatever you feel belongs to you, or I will cancel the debit order with my bank.
