Vodacom back to square one, useless

Vodacom, just back to the same scenario again. Though the issue was resolved, but now I get a large statement again. I did a review on Hellopeter about this same issue a while back. Last month I've received a credit from Vodacom, but now we are back to square one. This after I was assured that it will be sorted out, now I receive a large statement again for this month. Somebody doesn't know what they are doing. I'm really getting fed up with Vodacom now. To try and use all their channels that they have to resolve an issue, is really a waste of time.
