I had £2.85 on Curve Cash. I spent £2 at the Post Office and that came out of my underlying card, not automatically from Curve Cash. I then paid 88p on a second transaction in the Post Office straight afterwards, and that came out of Curve Cash.
How come the £2 did not automatically come from Curve Cash, when there was enough to cover the charge, only the second 88p charge?
Anyone any ideas?
