Telkom Bills for NO SERVICE!!!

I canceled my land-line and ADSL on 1 June 2020. It is now October and I still receive bills. The billing department can't tell me how much is still outstanding. Billing department says I have to visit my nearest Telkom branch (Paarl Mall). They print the bill, I pay and the following month the whole process starts again. Five months with NO SERVICE whatsoever, but I need to pay. Not happy at all!!!
