Invalid ITC listing

End of January 2015 I moved out of my old address well after my 3 year contract with ADT lapsed and sent letter of notice to [Email Removed] on 4 February 2015. The company still debited me twice in March 2015 and I reversed one of the transaction with my bank. On 10 April I spoke with Phumzile Mkwa**** to explain that I moved from my old address in January 2015 and I forwarded her a copy my cancellation email. On 17 April 2015 I received communique from ASHVEER DEWCHARAN about my account and sent him my bank statement to show the 2 debit orders. He responded saying the accounts department will determine whether I needed a credit or refund. On 26 May 2015 they refunded me and I have never received any communication besides their marketing newsletters. Today at the bank I was informed that I have been listed on ITC by ADT and refused my new cheque card. This came as a big shock to me because I haven't hear from ADT since their refund. This is irresponsible behaviour and shows they do not know how to manage their customer communication and processes. I want this ITC listing to be removed ASAP and an apology/explaination for this inconvenience
