I Cannot Buy Data

<p>I had a 12 month 2GB data bundle that was active from 21 April 2015 and was supposed to expire in April 2016. I visited a Vodacom store to try and purchase another 12 month 2GB data bundle and their system keeps saying my number is invalid. After several failed attempts, we gave the call centre a call and the lady said it may be because I still had some data that had carried over from April. She told me to finish that data and then try and load a new data bundle and that should work. So I left the store and returned the next day after having finished my data and their system still says that my number is invalid. I went to two other Vodacom stores thinking I'd have some luck but it was the same story. I then phoned the call centre again and the lady checked and said that she could see that there were no active data bundles but that she would call me back in 15 minutes because she had to wait for her system to load. I never heard from her. I phoned the call centre again and I spoke to another lady who could barely speak proper English and was very unhelpful. She told me that my data only expires at the end of May and that I'd have to wait until then to buy a new data bundle. How is this possible when the data bundle is only supposed to be valid for a year and it should have expired last month? I am now sitting without any data and it's expensive to keep buying single data bundles. This also means that I will probably have to visit a Vodacom store for the third time to try and sort this out. Surely their systems should pick up that my data bundle is finished and allow me to buy another one instead of making me wait until the end of the next month. This is so frustrating.</p>
