What happened to my airtime?

This morning I bought R1000 in air time. Suddenly this afternoon it is gone. I phoned Vodacom and was told the bank had not yet paid the money. In fact, they said the bank had not yet put the money on for the 20GB data bundle I had bought. They told me to phone the bank and denied the number from which I had received confirmation SMSes was a Vodacom number. I phoned again and spoke with someone else who said that I had 200GB of data available and that the R1000 was showing but had not yet worked its way through the system. I was told they would phone back 15 minutes later. About 30 minutes later I phoned Vodacom and was ask which call centre I had contacted. How am I supposed to know where 082 111 calls are routed to? He spoke to his manager, who spoke to a second manager, and I was told the second customer service agent would call me back \now". That was five to ten minutes ago and I have heard nothing. I need the airtime because I am getting on a plane to another country and am leaving for the airport shortly. Where is the airtime as well as the data bundle?"""
