Punching Data and never receiving it

For some reason my data bundle was depleted on the 7th after I purchased one gig data on the first. On receiving an SMS stating that my data bundle has almost been depleted I purchased yet another gig of data. As it stated that it has been successfully purchased and the money has been credited from my account. two days there after my airtime has been finished and the data as well. Without even being near my phone. So when calling the call centre having a battle with the person who assisted us basically telling me I'm lying about the data I have purchased withing two days almost R200 airtime and data has been used due to Vodacoms technical difficulties. And that I won't be able to get my money back nor the data that I never received after it said successfully purchased. And the service on queries is just as pathetic as Vodacom in store service
