I can't get hold of anyone to resolve this!!

I cancelled my ADT account when I moved in September, 2013. I received no response in 12 days, and so I sent another email to indicate that I am taking it as cancelled and would stop paying after the end of the month. I have subsequently received no contact, no invoices, no statements, no contact.<br> <br> I've recently pulled a credit report, and I notice that they list my account as still open, and past 30 days overdue. So I sent another email to find out what on earth was going on, and even offering to PAY the outstanding amount - anything, just to get this ridiculous outstanding note off my credit report.<br> <br> Despite receiving a ticket number (E833EDB55C6B9) exactly TWO WEEKS ago I have received no contact from ADT. In frustration I have eventually tried to escalate my query to Stuart James Clarkson via email (guessing his email addresses), and I STILL have received no contact from ADT.<br> <br> ADT, you have 48 hours to resolve this, else I will report this matter to the credit ombud, and take appropriate measures to ensure ADT is penalised.
