Cancelling an account

Hi,<br> <br> Trying to get through to Telkom in order to give my 30 days notice, 1 hr in and no response!! My line number is ***. All services including ASDL line must be stopped on 30 June 2015. I am leaving the country and closing the bank account so you will have no one to charge in July. <br> <br> Service center response times are awful and there's no information on whether the cancellation of a service may be done online or on email.<br> <br> Thank you in advance!
