Cheated by a shirt printing company

I am really pissed about the barcamp shirts. They were not only quite expensive but also the worst quality I have ever seen. They have actually a self-destroy mode, so better don't wash them. The company, aothun.vn, provided us not only ridiculous small sizesm but also a very bad printing. They also made it to change a sponsors name although we provided them all the logos. See below, how a shirts from Barcamp 2007 in Germany looks like after at least 20 washings, a Bangkok Shirt after at least 10 washings and the recent Barcamp Saigon Shirt after one washing.
