I've just posted to the Aus Facebook page and it's the only place I've been able to get through!  Apparently.

"We apologise for the inconvenience. This has already been escalated to our Technical Team and they are working on this as soon as possible. Once we will get an update, we will let you know."

Not much good for my auctions ending tonight!!! Still not happy at all! But at least they finally admit it's a problem!!!
