BAD SERVICE FOR CANCELLATION

I have given Telkom my one month notice on my DSL line on 4 Jan 2019. The cancellation of the sim, TIN and DSL was done, references received and due on 7 Feb. Since 4 Feb no internet, which isnt really the problem. On the 8th, I requested my invoice and saw that I am still being billed for DSL. Upon enquiring, the informed me that ons a cancellation for the TIN was done. Before 7 Feb I spoke to 3 different consultants and each confirmed that they can see cancellation for 3 services pending. I have since enquired about cancellation and now I dont get any feedback at all.
