Vodacom Incapable of Closing an Account

I have been requesting since July 2020 for my account *** to be closed. I send several emails to the cancellations department since beginning of August 2020 and have not received a response to any of my emails. I called again in the beginning of September after receiving no response to any of my emails and went through the process with your cancellation department to close the account. I called this week with regards to a separate matter and checked if the account has been closed. I was told the account was still open and again spoke to the cancellation department and was told the account will be closed and matter will be expedited and I will not be billed for October. At the start of October I was billed again for the account. I again called the cancellation department to get some answers. I asked to speak to a manager. I was told the manager would call me back and I'm still waiting. I have been a loyal Vodacom customer for the last 8 years and hold 3 different accounts. I will close all my accounts with vodacom if I don't receive confirmation that my account ***is now closed.
