Airtime not allocated

So yesterday I bought R18 Vodacom airtime around 6-6:30 am then I realized that the airtime was not allocated to me , I then used my ebucks points to buy R20 airtime as I needed to make a call immediately, still the airtime was never allocated , I then contacted Vodacom to enquirer about it and I was told that their system have not updated yet and that they will call me after an ‘hour’ such inconvenience but anyway I Waite for that hour and the lady called and still maintained that their systems does not show that I bought airtime I then asked what to do next as the money did go out of my account they told me that I need to print my statement and go to the nearest Vodacom shop so I ask my self now I have to take a taxi to town (36 fair )to enquirer about airtime which I bought such inconvenience I’m really not happy about this how izit my fault that their systems are not updating?? I once had the same issue with data bundles which I bought on s Sunday they were never allocated and I had to call Vodacom soo many time just to help Vodacom has failed me not once but twice
