Vodacom Voice bundle

I bought a just 4 u vc bundle on the vodacom app which I paid using my master card, the transaction went off successfully on my bank and it showed successful aswell on the vodacom app which I was supposed to receive an sms , the bundle was never credited. I called vodacom 3days later and they kept placing me on hold forever and no one could see my transaction, I was told to call my bank to check if the transaction was paid which I knew very well it was paid, still after the confirmation vodacom cannot see my transaction. The consultants seem not to know what they doing there.
