same problem again

bought data via Nedbank online banking on 24/12 - still not reflecting. Is this a Nedbank or Vodacom problem? Shouldn't be my problem! Vodacom call centre says data depleting cos of downloads - absolute nonsense - I have deferred downloads. Then call agent says it's a Windows 10 problem but he knows nothing about Windows 10, so someone will phone me back right now - still waiting. So yesterday, purchased via Std Bank - voila - registered immediately.
