It is impossible to cancel a Telkom line

I have used the self service portal to cancel my landline on the 29th of August 2018. On the 14th of September I received a SMS that states my final bill will be sent within 60 days.

This is not the case, I have been receiving bills as usual. When querying this with one of the agents online I have been asked to cancel again. I will not cancel again. I want my original cancellation and promise of final bill to be fulfilled.

With this I also request to be refunded the debit orders which has been taken after the promised 60 days.
