TELKOM USELESS CANCELLATION AND SOMMER EVERYTHING!

So I put in my cancellation for my account on the 30th of September for the account to be cancelled on the 31st of October. First of all after 10 days I followed up on my cancellation and they could not track it so I had to relog the cancellation. Finally the cancellation went through. Cancellation deparment called me to confirm the cancellation, confirmed it and I asked her when will the final debit be. She told me that it will go off on the 31st of December 2019. I also asked her if there will be any other debit orders going off and she said from this point on, no debit orders until the final amount. Sure as anything, 30th of November my account was debitted. I contacted them this morning and they say no it has to go off and that we must just wait and see what happends in the final invoice. Uhhhhh NO! Just because you have money to throw away like that doesnt mean I do. There goes my phone and bull security for the month.
