Cancellation of Contract

I have a contract at Telkom that has expired and wanted to cancel the contract seeing that it is on a month to month basis and I am no longer using this contract for almost the past 2 years as the phone was ****** just after I have taken it out. The phone was blacklisted and now it says that my line / number is suspended. Telkom are unable to cancel it because it is suspended and therefore they request that I must go in to a Telkom shop and un-suspend the number and then call in again to cancel. This utter bull**** that a loyal customer cant be assisted telepathically to cancel the account.
