Missing Airtime / Missing Cash?

I have purchased 2x R100 Vodacom airtime through my FNB App. This was on Monday 2nd August. Money has gone off, yet I have no airtime. On contacting FNB from that night until today, I am told the problem is with the service provider. Vodacom are insisting, from that night until tonight that the airtime isn't showing up on their system. Vodacom have been very accommodating and very clear with possible reasons for the issue. They have even tried to contact FNB on my behalf but FNB could not be reached. On the other hand FNB have barely been helpful and almost outright dismissive. When I asked for a reversal / refund through the Secure Chat, it was just ignored. Not only that, they also concealed the fact they have been having technical issues on their App.

I just want my R200 airtime or R200 back into my account.
