iStore took my money on FNB app, but no order produced

Yesterday I attempted to use FNB’s in-app ‘partner store’ to purchase an Apple Watch from iStore. I went through the full checkout process. At the final confirmation step, I was presented with an error “The partner is unable to fulfil your order at this time”. That would have been simply annoying, however, the money has been taken from my ebucks and primary bank account without any order being generated!

I’ve tried to contact iStore to see if they or FNB (or both?) must resolve the issue, but they are silent. iStore has taken my money but I got nothing in return - just the on screen error message in the FNB app. Now I’m trying to fight with FNB to get my money back.

This is not the first time I’ve had issues with iStore’s flaky systems. It’s just sad that such a big retailer can’t figure out how to do basic online purchase or customer service.
