Disappointing quality control

We were excited to receive our stickers, however we were shocked when we open the package, to find that the first few pages of the stickers were printed on the wrong sized sticker pages. This meant that there were 16 images printed, but they were printed over 6 large sticker cut outs, instead of the 16 per page we ordered. The rest of the stickers were fine, but it's a poor way to start, given it was our first order. The fact that it was the first few pages in the package, makes it even more disappointing, as it seems like there wasn't any quality control prior to sending. I can supply picture of this mistake, if required, as and we would like this mistake rectified and to be provided with the correct stickers.
