Vodacom app not working correctly

Just before the end of the month I noticed my minutes were low, so I decided to purchase a 50 minute once off bundle. The site said that I could not purchase a bundle and referred me to 111. After 2 days it showed that I had purchased 2 bundles. By that time it was not even necessary anymore. So I would like my money back. What is the use of purchasing a bundle but only been able to use it 2 days later? And then also been charged for 2 bundles? Vodacom's App sucks and is useless.<br> <br> Regards, Anthony
