Threatening bureau listing for unjust amount

I guess it comes as no surprise that these ones continue to send invoice for an amount charged after my cancellation and final payment for cancellation was made.

After I submitted all the necessary PoPs, cancellation confirmation emails from Telkom and even cross matching back to the statement their attorneys sent me, they tell me "Remember Telkom lists you with the credit bureau for this" without countering proof I sent.

Pathetic.
