Telkom avoids cancelling my landline!

I have cancelled my Telkom account per email, to no avail as this was not done and the amount kept increasing. I was alerted to this per SMS. I then tried to call the call centre, where I spoke to Asayda Mkalitskhana, who told me she could not cancel my account as they were offline. I keep thinking that this may be an excuse not to cancel my account because how can such a service provider be offline if this is exactly the type of services that they are trying to provide.
