Debit Order

<p>I cancelled my contract with ADT - which in essence actually expired in March 2017 - Last week I called to find out why the DO was still being deducted from my account if it's supposed to have been cancelled - I was told with a very *** attitude that I should have called to cancel it myself - so I requested it be cancelled - so this month it went off again and I reversed it - now I get a msg to call some woman named Mary Cherry who doesn't call me and doesn't answer her line either - I WANT MY CONTRACT CANCELLED and I don't want to be called I want all correspondence in writing -</p>
