Cancellation with Telkom IMPOSSIBLE

Over a month ago I issued a cancellation with Telkom. The account has been cancelled but not the line. Any time I call Vumatel they say that Telkom still holds the line and so there is no way to set up wifi with another provider. I need Telkom to release the line from the subject number so that I can establish fibre with another provider. I have spoken to more providers at Telkom than I care to count and every single one says that everything has been cancelled. I need help URGENTLY!!! I'm so so disappointed with Telkom's customer service. I'm stuck in a situation that I am receiving no help around.
