Hello, I pay for my ebay purchases using an Australia Post Prepaid Mastercard giftcard which I bought personally from the post office an load an amount of $500. Ebay has suddenly do not recognise the card or have asked to choose an alternative payment. I have checked the balance on the card and I have more than enough to cover the purchase. I had to then buy a couple of ebay gift cards at the local supermarket to cover the cost of the item instead. Could someone please shed some light on this? I'm confused.
