Must I beg Vodacom to close my account?

Can someone call me to vlose my account because when I call the cancellations department I don't get assistance.. this is the 4th complaint.

Another issue is my account is in arreas again when my contract ended in June.. I dont business with Vodacom anymore. I feel like I'm being forced to keep this contract they messed up to upgrade.

I will not be paying money I don't know. I wanta clear explanation how is my account in areas.

I hope this is the last time I'm complaining about the same company.
