Angry and frustrated

I am so frustrated with Telkom. I cancelled my broad band account online and receiced sms confirmation of receipt of cancelation on the 8th of October 2020 with reference number ***4. I was advised that the billings process will take 2 months. On the 12th of Oct 2020 i received another sms stating that my case number ***4 has been process and my cancellation order number is A. I called telkom on the 8th of December and was told that the cancellation request was not processed. The agent advised that he escalled the request and it will take 2 weeks. Called again 7 and 11January 2021, still nothing and again was told that they will log a dispute and received ref number ***1. On the 17th of January 2021 i received sms that said dear customer, your case number ***1 has been resolved...only to be billed again now in January 2021! I called today and are told the reason i was billed is because i cancelled on the 7th of January 2021! After explaining the same story for the hundreth time, im again told hold on so that a dispute can belogged? How many disputes is it gonna take for my service that i am not using at all to be cancelled!!!
