I had the same thing happen with Labcoat Ray and Whiplash. I got an error and thought the order hadn't gone through. I then ordered again successfully and got the 2 order confirmations.
I contacted Matty straight away and got the same answer, they couldn't do anything because they had already shipped. Now I have a boxed Labcoat Ray and boxed Whiplash sitting in my back room :tjlol:
