Vodacom is ripping me off in broad day light

I have been with Vodacom for more than 10 years now and I have never had bad service from them till today, besides the overpriced data I remained loyal to them... But I'm very angry right now, I bought 3GB for R300 and 6 hours later I still don't have my data bundles.... When I call customer care, the consultants don't even know what to do to assist me, the say they see that I did the transaction and they see my balance is not recharged but they don't know why... I mean how the hell am I supposed to feel when I'm getting such ****ty service, I want my data ASAP. R300 may not be a lot of money to Vodacom but it is hard earned cash to me. I want this fixed, and please hire competent consultants because the people you have working there are very lazy and not knowledgeable at all when it comes to how to assist customers.
