I have a fair amount of experience with SA, and the Voda group, and trust me this is just par for the course with Vodaxxx and nothing to do with RIM as dc/dc says.
You are quite right about them not being ready for the Storm but the same was true of Vodafone in the UK, marketing ran off before Tech were ready as is usually the case. But I know what you mean about the local support but to be fair that's a problem in a lot of SA business. Vodafone UK having well customer-service-trained reps saves them a lot when they have no tech knowledge.
I know you might want RIM to realise how crap Vodacom are but they base their relationship on global sales and it's probably better to make Vodacom big cheeses or Vodafone guys aware of the issue, not RIM.
