Contract cancellation

After several unsuccessful attempts to resolve my international roaming problems with Telkom, I have decided to cancel my contract. I filled in the form and emailed it off to them, only to receive the following bounced email report: The recipient's mailbox is full and can't accept new messages at this stage. Message therefore not delivered. Please try resending this message later. [Telkom SA SOC Limited. Registration nr : ***]<br> <br> Bravo Telkom, making life difficult in every conceivable way!
