unwanted upgrade and terrable service

I have had an absolutely terrible experience dealing with Vodacom. They called me March 2023 to do an upgrade. I did not want to do an upgrade, but the telephone marketer was aggressive and pushed me into it. When I tried to cancel the upgrade the next day, they said they would but never did. When I later realised, they never cancelled the upgrade I called again but they were no help. I have spent at least 30+ hours on the phone with them by now. Now they added an extra charge to my account for no reason.

I would recommend any one with a Vodacom account to cancel it immediately. I am even considering taking them to small claims court.
