Vodacom took my Airtime and data. !!!!

Yesterday I have purchased R130 and bought 1.5GB+1.5GB for R89 and after that I found I can’t access to the internet and I have 0kb so was shocked but I needed urgently data so I bought again R130 and went to Vodacom app and I bought 3GB+3GB for R159 also after very little I found no internet and I have 0KB so I called customer care and after holding 3 times each time 15 minutes the lady confirmed that nothing can be done. !!! I said to her I need either R260 which I paid or 9GB which I bought she said unfortunately nothing in getting so they really ****** me!!!! With excuse I bought YouTube bundle and this never happened!! I buy the data every week and was clearly no mistake and the mistake can’t happen twice within 1 hour difference!!.
