No response for cancellation

<p>I have a smart broadband 20gb month-month contract, sim only, i only had this because Telkom are useless and told me i had to wait 2 months for a landline. When they finally installed my land line, 3 months later, i emailed a cancellation form in April, and i got an error message that they mailbox was full, shocking. I then emailed it again a few days later, and then to a Telkom consultant in a store, and then again to cancellations, and still no response. I havent used the card, but now i will be charged for it because telkom dont responsd to the cancellation requests.</p>
