? about damged submission card

When my grades popped the other day I saw that my 78 OPC Murray got a 5 and I was a little puzzled, the cards arrived today and with the holder tilted I can see a crease that wasn't there prior to submission, it's not folded in half or anything but it's like they put a little to much pressure on the back of the card with their finger when they were removing it from the card saver. Is there any recourse for this, how would I even prove that it wasn't there prior to submission?
