Auction House Bid bug

The auction house has a bug. If you manually specify the gold amount to use when buying items and it is lower than the lowest price items, it won’t use that price. I suspect it’s using the buy-it-now price or something instead.

I’ve included screenshots here: Imgur: The magic of the Internet.

The first screenshot shows me losing ~9k gold when I bought 3 uncommon ether predator recipes. The 2nd and 3rd one shows me reproducing the bug. You can see me put in a 20 gold price, but end up getting charged 49 gold for it instead.

I’ve actually lost about 10,000 gold total due to this bug. Can I get at least the ~9k transaction reversed?
