Paid but no data received

I have 5 contracts with Vodacom, one of them ran out of data yesterday, i then received a pop up message form them to buy 1G data for R39 which will be deducted from my airtime balance, i did this and immediately the money was deducted off my account, It is now more than 24hrs later and still not received the data I PAID for. Very frustrating, i'm seriously considering to move all my contracts to a more reliable provider. I need someone from Vodacom to contact me, to either refund me or provide me with the data.
