Where is the data I paid for

I changed my bundle in December to get 10 gigs of monthly data instead of 6. Now, in Feb, Vodacom has not allocated my data to me. Customer care cannot assist. They escalated the query but it takes MINIMUM 4 WORKING DAYS to even get a response. There is no way to track or expedite the query so you're really just at their mercy :( The only solution is to BUY VERY OVERPRICED top-up data for which they don't offer a refund.
