Cancellation issues

I sent a cancellation notice to the cancellation department on 20 October 2015 in which I clearly stated that I want my subscription terminated by the end of November. In the beginning of this month (Dec.) the debit order was deducted from my bank account. When I confronted the cancellation department, they said that, \this is the first cancellation notification we have received from this email address."<br> <br> Please see a copy of my email to the cancellations department (on 20 October) below:<br> <br> From: Herm**** Gerber <br> Date: 20 October 2015 at 11:03<br> Subject: Cancel Subscription (end of Nov. 2015)<br> To: [Email Removed]<br> <br> To whom it may concern.<br> <br> Please cancel all of my subscriptions with Openweb at the end of November 2015. Please confirm that from 1 Dec. 2015 I will no longer have any subscriptions with Openweb and that all debit orders will already have been cancelled before the end of November 2015.
