The Proof looked a bit brighter & bigger than what arrived

I loved the artwork that was made as a final edit for submission and had it set for a die-cut oval cut for a 3"x3". The proof looked great & bright with good spacing. Yet, the dimensions were changed even tho the Promo was 50 Stickers for $19. However, once I received the final product, it the smaller than the die-cut oval shape intended and it was a whole 50 stickers. I honestly should have stuck with the circle die-cut since it would be closer to the original dimensions of 3"x3" as intended but since it was a promo for Sticker Mule it looks like a oversight.
