missing airtime and dat

Around 10am i purchased R110 airtime. Later around 1pm i purchased another R110 and 1gig of data. Two hours later I try to make a call and the balance is zero on both airtime and data. When i call the call center to find out what happened, im told the system has not updated yet, and that I should call after 24hrs. Where is the data and the airtime vodacom?
