No response on cancellation

<p>Last month I phoned Discovery card to cancel my card. I haven't used it for ages and have been charged monthly for it including for discovery miles which I never signed up for. I've been procrastinating cancelling it because I expected it to be a painful process. The call centre agent was helpful and sent me a form to fill in and assured me it would be processed before the next charges to my account. I immediately filled in the form and emailed it to Discovery. I heard nothing. I was charged another month. The debit order went off on the 1st. I'm now urgently trying to get my card cancelled before the next charge puts my card out of zero balance. I've sent numerous emails with my cancellation form and have still to have any contact from Discovery. Please stop *****ing my money and cancel my card.</p>
