ADSL and Phone Line never cancelled after upgrade to "better" internet

I requested the cancellation of my copper services (Telephone Line and ADSL) on 9 April via the website after going to a Telkom shop and being told I must do it online, as well as phoning and being told to do it online. Reference numbers: ********** 2 and ********** 3. It has been two months and I am still getting billed for BOTH services! I do not want to pay for the rental AGAIN for June, what does it take to cancel my services? Why must I go to Fibre of Telkom LTE if I will be billed for that AND the services I want cancelled? TELKOM said I must upgrade to LTE but now I still have to pay for ADSL?
