So here's another way that QFCash makes no sense.
I had EUR26.00 left on the card but wanted to buy something for EUR27.50. Easy, transferred some USD across, taking the hit for a second time on the big margins (ie. It's fee free, but rate is woeful). Anyway, confirmed EUR27.50 available.
Next step, I tried to make a EUR 27.50 purchase. Response was "Error: Insufficient funds". Ok, maybe QFCash currency transfer is a bit slow. Waited until next day and tried again, same problem. Waited the weekend and tried again, same error. I did check that the merchant was charging in Euro, not Australian dollar.
Gave up and rang QFCash (endless menus, etc) and finally spoke to a human who asked, no kidding, about 9 security questions. In the end he said that he could see the transaction in question, a EUR27.50 purchase had been declined for insufficient funds, and that I had exactly that amount in the wallet. Hmmm, seems odd.
Anyway, reading off a script he says that the merchant had charged EUR27.50 but my account had slightly less than this amount available due to the AUD:EUR exchange rate.
What!?! I thought the point of the QFCash card was to operate in a foreign currency. Actually, no. In their wisdom QFCash have decided to sting customers a margin on 'exchange' when loading FX, but then keep the actual money in AUD until they spend it. I had understood that QFCash marketing advertised "locking in" an ex rate for peace of mind. I'm pretty sure if the rate changes in favour of the customers QF cash wouldn't suddenly credit my account with the difference.
What a cough product. You'd think that bullet point 1 on the business plan would be: when customers try the product, damn well make sure it works.
