Terrible Service no one in "accounts" can assist properly

<p>After noticing no more response vehicles in our area, we decided to end our service with ADT in December2016 . That same day I emailed the very "helpful" contact centre ********** To give cancellation of my services. The December debit order with the yearly radio fees went off which was fine as according to me my new security company would come into effect January 2017. I received ONE sms on 22/12/2016 telling me to contact ADT regarding my cancellation. They called me once which unfortunately I missed the call and no answer when i tried to return the call. The first sms I received to test my alarm was on 25/12/2016 and it stated that I need to call office hours 9am-3pm mon-fri. 3 days after I sent the email informing of cancellation. January I phoned the call centre once again after January dt order went off, the person informed me that i need to give one month written notice which no where did I sign this is not a cellphone contract i cancel you come pick up your receiver business done. The call centre can not assist me as they say i owe money they can not tell me for which months they just send link saying total owing FOR WHEN they cant even give me dates?? I sent email again with the payment confirmation for the exact amount outstanding and telling them i cancelled to date no one tried to help or gave aknowledgement. Today i receive FINAL demand for more money assuming this would incl Jan-Mrch 2017 as well. This service is horrible i will not pay one cent after my cancellation. If I owe any money why can no one tell me precisely for which months according to them i am outstanding????? Please can anyone assist me that has a understanding of how accounts work, you cant send anyone an amount owing and not stating for when these monies were due/payable. I am sure no one will pay. I have all necessary emails sent as well as proof of payment for the First amount of R1500.00 outstanding. This FINAL DEMAND must be sorted out ASAP!</p>
