Airtime Missing

This morning I bought airtime worth R110. I had some data bundles on my line as well. I didn't make any calls and my data connection was off. I took a nap this afternoon and when I woke up in had missed calls. When I was returning the calls I was told I have insufficient funds to make the call. I regarded with 12 rands. <br> <br> Then I called Vodacom and was told that the airtime was used out of data bundles. Really ? The whole R110 while I was sleeping and cooking. <br> <br> Can I please have my airtime back this is day light *******.
