Data bundles not working

I have now twice purchased the 7 day data bundle for R 159 on the Vodacom app with it not responding/working for about 2-3 days. Thus leaving me with 10GB of data to use in 3 days. I am a long standing contract client (more than 20 years) I emailed their complaints line and after my second email request I received a call back from them. After a 10 min conversation of going back and forth the final take home message for me from my service (or lack thereof) provider was: "contact us immediately once you cant access the data you just purchased." I asked them how they would answer me since I have contacted their customer services line before and never once could the issue be resolved nor have they offered any data or airtime or anything to try and comfort a customer that feels ******. There is never an issue with the payment and Vodacom deducting funds. NEVER. But when it comes to data packages not working and someone tells me to switch off my phone when it happens, I want to loose my mind! Vodacom you have got access to all our purchasing history, data usage trends and phone calls. Then its easy to access and try and sell you more options via telemarketers, but when I asked them to look up my purchase dates and see that for days after the purchase no data was used because the data was stuck and not responding even though the payment went through via airtime, they still could not answer me or offer me anything. Worst of all is that there are no other options in SA. All services are up to ... Thanks for nothing. P.S. won't be surprised if they get the same agent to call me
