Telkom Fixed Line cancellation woes

Why should it be so difficult to get a fixed line cancelled? I sent the completed form and copy of my Id to both ********** and ********** only to be informed that their mailbox is full...?? Another email to ********** at least produced a reply, instructing me to do the cancellation online. I found it impossible to get to the spot where I could request a cancellation. "Manage Account" produced "No accounts to display". An attempt to link my landline number to the profile, produced "Cannot associate this service, it required approval". A call to the call centre redirected me to the website. What on earth should I do now? Get my lawyer to write a letter threatening an application for a declaratory order ?
