Vodacom does not care about people's lives

I have an account at Vodacom and in September it happed that I withdrew all my money from my bank account it so Vodacom did not debit for the month. However the money was debited double on October and its December now but my account shows that I'm in areas.... Yesterday I failed to get a study load at my bank because of this. I mean I have proof that I paid but they show my account in areas...
