Don't want to cancel my debit order after moving

<p>So irritated that i have to spend so much time to cancel a simple subscription with you guys? When we had problems with burglars and contacted you guys about out alarm that was faulty and had problems you told us 3 TIMES you would send someone to check it out and never did, about 2 times the alarm went off you guys came to our house but just drove away because you said you had no Master Key? After we repeatedly phoned and told you that YOU have the master key. So now we moved and we really don't want ADT again and I have cancelled my subscription with you guys 2 months ago but you still want to debit money from our account and sms my mother that she should pay? I will never ever again suggest you guys to anyone out there. </p>
