Cancellation of account

I app**** online for a sportscene account 14/08/2015. On the morning of 15/08/2015, i called their new accounts department to cancell the approved account. The agent put me on hold, 15secs after answering. The Team leaders are screaming in the background. However, the agent advised that the application has been discarded. And that an sms would be sent as confirmation. I am still awaiting this confirmation, as i want evidence that it has been cancelled.
