Please cancel my paypal payment

Hi, not sure in what section I should post this but yesterday I emailed twice asking for my paypal authorisation payment to be cancelled but have recevied no reply. Communication prior to this was very prompt. It was processed through the wrong bank account that I have registered with paypal and will cause me problems is processed. Once it has been cancelled I will set it up properly and re-process the authorisation.
