Terrible customer care

Vodacom have overbilled me. I called more than a month ago and was assured that the problem had been fixed: that I would not receive a corrected invoice, but the debit would be correct. I received smses saying the matter had been closed.

Needless to say the wrong amount was debited. I've been trying to speak to Vodacom for 2 weeks alreaddy (since the debit went off). Their customer care line (135) constantly says they have higher than average incoming calls and you may wait longer than usual. They suggest that you consider self-help options and then the automatic selection gives you options but none of them are to speak to a person. They all lead to a computer.

Today they don't even tell you that it's busy, they just put you through to a computer again, which ONLY offers self-help options.
