Trying to cancel ADT subscription, no response

I am moving house and have to cancel my ADT subscription. I phoned the call centre and was informed that I need to give 1 month's notice. So on 27 August I sent an email to [Email Removed] as per the call centre agent's instruction. Immediately received an automated email response and ticket number.<br> <br> Then, nothing! 1 week and 4 phone calls later still nothing! Every time I phone I am told that they are very busy and will get to my email. My concern is that whenever they get to my email I am told that it is too late and the next debit order will go off again.<br> <br> Very poor service, but what can I expect, I am cancelling my subscription. Maybe what I need to do, is get in my car, drive to the bank, stand in line and stop the debit order. Maybe then someone from the accounts department will be quick to phone me. <br> <br> Thanks ADT!<br> <br> From a loyal customer.
