Terrible service

I have a month to month service with Vodacom for Fibre. I called to cancel the service more than 30 days in advance for end of March. Since the 26th of February I've had no connection. they cannot restore it because they do not know what is the issue. I have spoken to more than 5 agents and they cannot assist. This morning they debited my account in advance for a service that they are no longer providing. I called the manager who was rude and still couldn't explain what was going on. They are the worst providers.
