ADT Fail to Fix Faulty System still under Warranty

I have on 3 separate occasions requested technical assistance from ADT as my alarm is faulty and keeps going off whenever I set it. My 1st call to them was about 8 weeks back! My last call just over 2 weeks back.<br> <br> Despite being promised a call out to fix the fault I am still without a working security system. My insurers will decline any claim made because of ADT's failure to keep my system in working order! I am refusing to pay for next months debit order as I have paid them for the past two months for what? Continual refusal or failure Io fix a faulty system still under warranty.<br> <br> Our agreement is they provide me with a working security service - I pay them for providing me with this. I will NOT pay for non service. If they debit me I will get the bank to return it. All bank charges will be for their account. I have had to do this before so ADT knows I am a man of his word! You fix, I pay, BUT not for October as I have already paid you in advance lats month! I have had enough paying for non service. I pay for what I am given. Nothing more, nothing less. If everyone in SA would do the same we would see massive change in business ethics.
