Should be a white T-shirt but it has yellow stains on it

I was very excited for the T-shirt but when it came, theres was a huge rectangular "yellow stain" all across the front. My guess is they didnt erase the white background on the design, rather just leave it white, which in turn got printed and is, of course, different shade of "white" as t-shirt and as such very visible. Also the design was printed way too much to the side, almost next to the armpit. This is my first bad experience with Sticker Mule tho. Hopefully the last as well.
