Vodacom *****ing money via the vodacom app

I purchased a data bundle on the 1st of December after getting confirmation that the bundle was purchased I didn't receive the bundle. After sending a inquiry to find out what happened I was told the investigation will take up to 48h in which I inquired what was going on and was told that the issue was being investigated. On the 4th of December (today) purchased another data bundle and the exact same thing happened so went to a vodacom store to find out why are they taking my cash with out supplying me my bundels after 3 hours of trying to get my phone working I was told that nothing can be done as they haven't received the fund. Which I went to the bank and got reference numbers for the transactions, went back to vodacom and the answer I got was they will investigate and contact my by Tuesday next week.
