ADSL account still not cancelled after the upgrade to Fibre

Kindly Cancel my ADSL account, I have upgraded to fibre. The ADSL line was cut, I saw the technician cutting the ADSL wires. Only the fibre line is ACTIVE.

I am still being billed for ADSL. How can I have two accounts? Who has a fibre and adsl account at the same time?

Under my login for Telkom account it has been showing the following from September:

"We are busy investigating the cause of the problem."
