Can Telkom's service get any worse

I cancelled an internet service with Telkom the 8th of December 2017, I am still getting billed every month after sending through cancelation forms monthly to Telkom and all that is said every time is, they will escalate the problem. I have also gone to the local store many times where they have sent e-mails on my behalf to customer care and after 9 months I've been told that the service has been cancelled but due to their delay the accounts department handles it as an outstanding amount and i've been told by Telkom to take it on with account myself. Seems impossible to cancel an account with Telkom and no one really helps with problems or get back to you
