CANCELLING OF LINES

I have cancelled my EXTRA lines in MARCH 2020. Up to date the lines is still not been CANCELLED!!!!! Due to this not been cancelled I still need to pay a HUGE AMOUNT, for my main line not to be disconnected. THIS IS UNACCEPTABLE. Now I need to pay every month because TELKOM cant do their job properly!!!! I also cant get hold of any one at TELKOM.

IF TELKOM IS GOING TO DISCONNECT MY MAIN LINE AGAIN, I WILL SUE TELKOM FOR LOSS OF INCOME!!!!!!!
