VODACOM FIBRE BILLING ISSUE

I am extremely unhappy and disappointed with the service at Vodacom. I received a wrong bill and queried it immediately on the day 8th August, but the wrong amount was debited still om 25 August and I was told they can only fix this the following month. Fast forward to the following month (September) the query was closed and the amount on my statement is still incorrect. This is very frustrating as I have to go through 10 clueless people before I can reach someone who claims to understands and attempts to help but still, this issue is not resolved. There is such a disconnect between departments and I literally need to explain my story 10 times every time I call to follow up. The person in charge of my issue the last time only communicated through email and never followed up with a call, this is frustrating as I tried to reach out via email as I did not have his direct line but he still closed the query without finding out if I am satisfied or not This is really unacceptable and a waste of my time. I am definitely cancelling my contract
