lost my data and airtime

I loaded R12 onto my account to pay for the advice I made few days back. I loaded another R12 and bought 60BM of data which costs R6. I then tried to access the Internet and it could not go through. When I checked my account, the data bundles and airtime where not there. I called the vodacom call center and they referred me to Autopage (which, according to the woman from the Vodacom call center, closes at 22h00). I called Autopage and I was not attended to. I tried calling them again and the same thing happened. I just want to know what happened to the airtime and data bundles that I loaded onto my phone, and if it would be possible to get the airtime and data bundles back since they were never used
