Sms bundle not reflecting

I purchased prepaid airtime which would not load - I had to go to the Vodacom shop to have this loaded. I then purchased a 100 sms bundle with some of the airtime I purchased on the self help option. I received a sms confirming that the 100 sms bundle was deducted from my airtime, however when I checked my balance I have zero sms's. I tried calling customer service but it is almost impossible getting through to a human being that I can speak to.
